5. USB Modem and Ubuntu.

   With Ubuntu we can recommend these instructions

6. How does USB Modem software differ from other programs like PDAnet?

   Technically speaking, USB Modem implements USB CDC ACM protocol, while PDANet uses ActiveSync to transfer data over USB. In practice that means that USB Modem does not require ActiveSync and supports not only Windows but also Linux and Mac OS X (including Leopard) desktop operation systems. As for Bluetooth connection, technically there is no difference.

7. Does USB Modem support Mac Wi-Fi Internet Sharing?

   Yes, it does. Using the built-in Airport wireless networking and the "internet sharing" system preference you can share the USB Modem/Treo connection (both Bluetooth and USB) at the same time on two Mac computers.
   First, make sure the "host" is connected to the internet via USB Modem and the PDA.
   Second, open System Preferences on the host MacBook Pro and choose "Sharing".
   Select enable Internet sharing, and choose the connection, and the method of sharing (Airport). See this Wi-Fi Internet Sharing screenshot.
   Then on the "guest" MacBook Pro that wants to share the internet connection, from the airport icon in the Mac's menu bar, select the name of the hosting computer with the USB Modem internet connection.

8. The New Network Port Detected does not appear on Mac OS Leopard

   Please go to System Preferences/Network. Then click on the + on the bottom left of the window listing the ports. That will create a new service. After that please select the USB Modem item in the list, that will then add the new network port.

9. "No dial tone" error, error 680.

   Windows desktop: the "No dial tone" error usually appears when something wrong is selected in the Connection Properties -> General tab -> Modems list. Tell us what is selected in Connection Properties -> General tab -> Modems list (USB Modem must be active at that time).

10. WM USB Modem crashes when trying to connect.

    Make sure you stopped and closed ActiveSync.

    1. Disable USB Modem
    2. Kill the ActiveSync application
    3. Restart USB Modem
    4. Attempt to bring up PPP from your computer
11. WM USB Modem returns a NO CARRIER error.

    Make sure you stopped and closed ActiveSync.

12. Guidelines for using Palm USB Modem to connect via BT to a Nokia N810.

    All you have to do is to install USB modem on your Palm, disable the built-in DUN (option "suppress built-in DUN" in the USB Menu on your Palm in the top left corner), set it to Bluetooth mode and then you can go to setup the Nokia N800, N810 or Nokia 770 with just the Bluetooth connections installed on the Nokia device. No extra files are needed.

    Similarly, USB Modem works in Bluetooth mode with TomTom ONE and TomTom ONE XL devices.

13. Palm USB Modem is frequently disconnecting when used with Mac OS X Leopard.

    Please try to enable or disable the "Send echo packets" option in the Network Properties (under PPP Options...)

14. USB Modem is frequently disconnecting from a Windows desktop.

    Try to toggle the options in the Connection Properties -> Networking tab -> PPP settings.

15. "Failed to enable modem mode" error when using Palm USB Modem.

    Try to enable the "suppress built-in DUN" option in the USB Modem menu (in the top left corner).

16. I used WM USB Modem for two weeks and had at least 20 connections, suddenly the "Enable" button became unclickable.

    If you were able to use WM USB Modem and then suddenly the Enable button stops functioning, it means that the trial has expired. For some reasons on Motorola Q the trial expiration dialog may sometimes fail to appear.

17. Under Mac OS the following error occurs: "A crossed connection has been detected. Please verify settings and try again".

    Make sure that the correct modem script is selected here - Leopard script selection. Please note that if you have a CDMA device, then you have to select "Mobile Stream CDMA". Please check your username and password as well.

18. "Service Connecting Progress: Error: Cannot connect to the internet because a dial-up networking session is active. End the DUN session and try again. OK" The Bluetooth modem it disconnects and the laptop says: "The connection was terminated because the other side is not responding. Please try again."

    Try to enable the "suppress built-in DUN" option.
    Please make sure that no program (such as a mail or a chat application) on your Palm tries to check the internet periodically. When the modem session is active it is not possible to use Internet from the phone itself. So when an e-mail app tries to connect to Internet it fails because the resource is already used by the USB Modem session.

19. Does USB Modem use call time minutes or a data plan?

    USB Modem uses a regular data plan.

20. If I receive an incoming call while using USB Modem I get disconnected from the internet temporarily. Is that normal?

    Yes. This is an expected behaviour. You can try to look for third-party applications which can disable incoming calls.

21. How to obtain Sprint user name and password.

    Sometimes blank credentials work, sometimes do not. Please see here for the Sprint password/username retrieval.

22. When USB Modem is activated, the network connection on my phone turns off and I can't seem to get it back on without turning off USB Modem.

    USB Modem uses the internal phone modem to provide the connection and since this is a single-user resource, the on-phone Internet connection will not work.

23. AT&T/Cingular credentials

    If you use Cingular Blue, AT&T or Nextel:
    username: blank
    password: blank

    If you use Cingular Orange:
    username:
    password: CINGULAR1
    More settings can be found here, although they are about Blackberry, the same password/username settings apply to Palm and Windows Mobile.

24. Verizon credentials

    Usually the Verizon credentials are as follows:
    username: NNNNNNNNNN@vzw3g.com
    password: NNNNNNNNNN
    where NNNNNNNNNN is your phone number;
    Please note that sometimes with Verizon the dial number might be #777 and the username and password might be blank.

25. I purchased Palm USB Modem but I am still getting a message about a trial period.

    Looks like the full version did not replace the trial one for some reason. Completely remove the trial version on the device (USBModem.prc and BtDunMgrLibStub.prc), soft-reset it. If you do not know what "Soft Reset" means read these instructions on soft resetting your Palm

26. I have Windows XP Pro. When I open the modem status window and click properties, select usb modem, and click configure, 921.6 kb/s is the fastest speed it allows me to choose.

    That is a dummy number. The real speed could be higher or lower than this value. You can try to measure the actual speed using speedtest or mspeed.

27. How do I get the USB Modem driver to install?

    Please note that USB Modem has its own drivers. Please see the detailed instructions on installing these drivers in the attached USBModem_UG.pdf (USBModemWM_UG.pdf). These instructions differ depending on a desktop OS.

28. Sprint HTC Touch or Treo 700wx won't work for bluetooth.

    Please note that you should see two DUN services available on this mobile device. One is a standard "Dial-up networking" and another is "Mobile-Stream DUN". Make sure to use the second one.

29. "Error 678: There was no answer" when I try to connect.

    First please check the basic connection to the Treo. To do this, enable the USB modem mode, go to Control Panel -> Modems -> Properties and select Diagnostics. If the exchange is ok, send us the log file. See the last question in this f.a.q. on how to send log files.

30. While installing USB Modem I get the following error message: "Cannot create a stable subkey under a volatile parent key."

    Before the USB Modem installation please disable any firewall or antivirus software. After the installation is complete, you can enable this kind of software again.

31. How to update a USB Modem driver on Windows Vista?
    Please try the following:
    1. Enable the USB modem mode on the Treo and connect it to the PC with a USB cable.
    2. Launch Control Panel -> System -> Device Manager. Do you see the USB Modem or Unknown USB device under "Modems" title in the device tree?
    3. If you see an unknown device, open its Properies -> Update driver and point the installation wizard to the usbmdmtreo2k.inf file.
32. Is it possible to use Palm Treo/Palm Centro as a Bluetooth modem for T|X or Zodiac?

    We have several successful users' reports on that. You can enter USB Modem information (Connection, User Name, Password etc.) in the T|X Prefs - Network section.

33. I cannot select a modem script, there is no selection list on my Leopard. Mobile Stream is not listed in the drop down menu of Modems from the Networking page.

    Press Network Properties - > Advanced, then select Modem tab and setup the scripts in the Vendor/Model pull-down lists as described in the following screenshot - Leopard Modem scripts selection. Please note that the screenshot shows GSM, you have to use a CDMA script if you have a CDMA phone.

    Make sure you have selected "Other" in the Vendor pull-down list in the Modem tab of the Treo network port settings

    If you still do not have the Mobile Stream CDMA script there, please try to put the scripts in the "/System/Library/Modem Scripts" or in the "/Library/Modem Scripts" folder.

34. My problem is not described in this guide.

    Please tell us your desktop OS, your device model, your carrier, the exact error message (and/or the exact step in the installation guide which caused difficulties) and send us a log file.
    Sending a Mac log file: enable the "Use verbose logging" in the USB Modem network port properties under PPP Options... (in Mac OS Leopard you should go to System Preferences - Network, then select USB Modem and press the 'Advanced...' button and go to the PPP tab), launch Applications -> Utilities -> Console, set it to show the /var/log/system.log and try to connect again. You should see the lines appearing in log. Copy/paste them into the e-mail and send us.

that says that a new network port called Treo 650 USB Modem (or according to your actual
device) has been detected. Press the OK button to proceed. Sometimes you would not see this
message box. This might happen if the Network panel was launched too fast after enabling the
modem mode on the Treo and the system did not enumerate the USB bus yet. In this case close
the System Preferences, disable the modem mode on the Treo then enable it again and repeat
this step.
5. Select the Treo 650 USB Modem item in the Show pull-down list.
6. Properties for the network port will be displayed. Go to the Modem tab and select either
Mobile Stream CDMA option (for CDMA 1xRTT or EvDO networks) or

menu. It is recommended to disable the Wait for dial tone before dialing option.
7. Go back to the PPP tab, type in the optional Service Provider name (e.g. Internet via Treo
USB Modem), fill in the Account Name, Password and Telephone Number fields with the
values you got from your provider. Usually the number is #777 for CDMA networks and
*99***1# for GSM networks.
8. Now press the PPP Options... button and disable the Send PPP Echo packets and
Use TCP header compression options in the dialog then press the OK button. Note that with
Verizon you may actually need to enable the Send PPP Echo packets option to prevent
disconnecting after short period of inactivity.
9. Press the Apply Now button to save the network port settings.
10. Press the Dial Now button. In the displayed dialog press the Connect button to start the
connection. Note that for GPRS or EDGE connection the additional message box will appear

setup (step 12) if you have such a device.
To connect, set the Treo Bluetooth in the discoverable mode, launch the USB Modem application, set
the Connectivity method to Bluetooth, enable the modem mode on the Treo and start the connection
on the Mac. There are plenty ways to do this. The easiest one is to tap on the phone connection icon in
the right side of the Mac OS X menu bar and select the Connect item in the pull-down list. For GPRS
or EDGE networks the additional message box will appear asking for the access point name (APN).
Type it in and press the OK button to continue connecting.
To disconnect, choose the Disconnect action in the connection's pull-down menu.
3.4.1. Configuring a Bluetooth Network Port

Continue button.
7. The Gathering information about your device dialog will be displayed. Wait until the
Continue button becomes available and press it.
8. The Pairing with the mobile phone dialog will be displayed with the passkey code. Enter this
code on the Treo to pair it with Mac.
9. Enable the Access the Internet with your phone's data connection option and press the
Continue button.
10. Fill the Username, Password and GPRS CID String (this is a dial number, use #777 for
CDMA networks and *99***1# for GSM networks) with the correct values. Also select either
the Mobile Stream CDMA option (for CDMA 1xRTT or EvDO networks) or the
Mobile Stream GSM option (for GSM GPRS or EDGE networks) in the Modem Script pulldown
list and press the Continue button.
11. Press the Quit button to close the Bluetooth Setup Assistant and return to the Bluetooth
control panel.
12. Additional setup is necessary for Treo 700p/755p or Treo 680 unless you selected the
Suppress Built-in DUN option on the first launch of USB Modem. Proceed directly to step 13
if you have Treo 650.
1. Select the just added device in the Bluetooth Devices list and press the
Edit Serial Ports... button.
2. Make sure that the entry with the Mobile Stream DUN service is enabled and listed
before the entry with the Dial-up networking service then press the Apply button.
13. Go into Mac OS X System Preferences -> Network, select the Bluetooth item and press the
Configure button.
14. The properties dialog for the Bluetooth connection will be displayed. Press the PPP Options...
button, disable the Send PPP Echo packets and Use TCP header compression options then

press the OK button. Note that with Verizon you may actually need to enable the
Send PPP Echo packets option to prevent disconnecting after a short period of inactivity.
15. Press the Apply Now button and close the Network control panel.
3.5. Upgrading
To uprade USB Modem to a new version just install the new USBModem.prc file on the Treo and copy
new versions of the Mobile Stream CDMA and Mobile Stream GSM files to the
/Library/Modem Scripts folder on your Mac.
3.5.1. Upgrading to version 1.50 or higher
This note is valid only when upgrading from USB Modem version 1.42 or earlier to version 1.50 or
higher. Mac OS X will display a message saying that it can't find the device when you try to connect
for the first time after installing the new version of USB Modem on the Treo. This is a side effect of
the important bug fix and should not be considered an error. To restore the normal operation,
reconfigure the USB Modem network port as described above.

4. Using USB Modem with Linux
4.1. Requirements
Modern Linux distribution with the USB CDC ACM class support in the kernel (either built-in or as
module cdc-acm.ko) is required.
4.2. Installation
Unzip the USB Modem archive anywhere on your Linux computer. Install USBModem.prc in the Treo
RAM (not a card) using a HotSync or by other means.
4.3. Setting up a PPP Connection
1. Obtain the user name, password and dial number from your wireless provider. For GSM
networks the access point name (APN) is also required.
2. Copy either ppp-script-edge-template (for GSM GPRS/EDGE networks) or ppp-script-evdotemplate
(for CDMA 1xRTT or EvDO networks) file from the USB Modem distribution to
/etc/ppp/peers/ppp-script-treo (you may need to create the path manually), replacing the
USERNAME and APN (for GSM only) words with the correct values.
3. Add the user name and password line from the pap-secrets-template to the /etc/ppp/papsecrets
file, replacing the USERNAME and PASSWORD words with the correct values.
4. Test the connection.
See the drivers/linux/mts folder for the complete pppd example scripts tuned up for the MTS GSM
operator.
4.4. Connecting via USB
First of all, configure the Linux PPP connection as described in the Setting up a PPP Connection
section above.
To connect your Treo using a USB cable to the Linux computer, start the USB Modem application on
the Treo, set the Connectivity method to USB and enable the modem mode. Now type in the
command prompt:
bash-2.05# pppd /dev/ttyACM0 call ppp-script-treo
It will print how the connection setup is performed. If it was successful a new network interface will be
created (usually ppp0). The only thing left is to copy the content of /etc/ppp/resolv.conf to system-wide
/etc/resolv.conf for proper name resolution:
bash-2.05# cat /etc/ppp/resolv.conf > /etc/resolv.conf
Note: for some newer Linux distributions (such as Fedora Core 3) do the following instead of the above
step:
bash-2.05# ln -s /var/run/ppp/resolv.conf /etc/resolv.conf
Page 10 of 12
To disconnect, stop the pppd process like below:
bash-2.05# kill
4.5. Connecting via Bluetooth
Generally a setup consists of two major steps:
1. Configure the RFCOMM channel to Treo and get a device node for it. The exact meaning of
this depends on the Linux Bluetooth stack and distribution.
2. Configure the PPP connection as described above and start just like with the USB case but use
the device node from the first step instead of the /dev/ttyACM0
4.6. Upgrading
To upgrade USB Modem to a new version install the new USBModem.prc file on the Treo and update
the pppd scripts from the new templates.

5. Troubleshooting
5.1. Cannot Connect via Bluetooth on Treo 700p/755p/Treo 680 or Centro
Try to use the Suppress Built-in DUN option in the USB Modem menu.
5.2. Windows cannot find the USB driver for palm Centro
Make sure to reinstall the USB driver from the USB Modem package.

USB Modem

USB Modem allows you to use Windows Mobile based devices as a USB/Bluetooth modem for connecting a desktop/notebook computer to the Internet. To surf the Internet from your PC you will need only a USB cable or Bluetooth adapter and a smartphone/communicator with GPRS/EDGE service or CDMA 1x/EvDO data plan. However, for more reliable work with Sprint or Verizon carriers you may need to purchase their tethering plan.

Please note that if USB Modem stops working after you have upgraded to Mac OS 10.5.5, you should try to delete the existing USB Modem-related network port in System Preferences, then create it from scratch as described in the manual.

Features

• Support for Windows Mobile 5.0, 6.0, 6.1 devices
• Support for Windows Vista/XP/2000, Mac OS X and Linux operating systems
