3. Using USB Modem with Mac OS X
3.1. Requirements
Mac OS X version 10.4 (Tiger) or higher is required for the USB or Bluetooth connection via Treo
with USB Modem installed to work. Mac OS X version 10.2, 10.3 or Mac OS X 10.1 may work too
but are not officially supported. Moreover, the AppleUSBCDCDriver Patch (downloadable from
Apple's site) has to be installed for Mac OS X 10.1 for the USB connection support.
Mac OS X 10.5 (Leopard) was in closed beta at the time of the release but should be compatible with
USB Modem.
3.2. Installation
Unzip the USB Modem archive anywhere on your Mac. Install USBModem.prc in the Treo RAM (not
a card) using a HotSync, Missing Sync or by other means. Also copy the Mobile Stream CDMA and
Mobile Stream GSM files from the drivers/macosx directory in the unzipped USB Modem distribution
to the /Library/Modem Scripts folder on your Mac.
3.3. Connecting via USB
You need to configure the USB Modem network port before using the Internet connection. See the
Configuring a USB Network Port section below.
To connect, plug the Treo using a USB cable into your Mac, set the Connectivity method to USB,
enable the modem mode on the Treo and start the connection. 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. Note, if you see the Mac OS X message saying that it can't find the device, though
the Treo is attached and modem mode is enabled, go to the System Preferences -> Network dialog,
choose the Treo 650 USB Modem (or according to your actual device) configuration panel, press the
Apply Now button and try to reconnect.
To disconnect, choose the Disconnect action in the connection's pull-down menu.
3.3.1. Configuring a USB Network Port
It is assumed that USB Modem was successfully installed as described in the Installation section
above.
1. Consult your wireless provider on the important parameters that are necessary to setup the
connection. These include the dial number, user name and password (the latter two may be
blank). For GPRS or EDGE connections the access point name (APN) is also required.
2. Connect your Treo with the USB Modem application installed to the Mac using a USB cable.
3. Start the USB Modem application on the Treo, set the Connectivity method to USB and
enable the modem mode.
