USB CDC-ACM Virtual COM Port Installation
Windows XP (SP3 or greater), VISTA, 2003 Server, Windows 7 (32-bit or 64-bit), Linux (Kernel 2.6.xx using CDC-ACM module)
are supported.
For Linux, a 2.6.28 kernel or greater is required. The standard CDC-ACM driver will work.
Note: Certain levels of Windows have an issue with their CDC-ACM driver (Usbser.sys). If you are having connection problems
(file download, web pages not loading) your version of Usbser.sys must be updated. Microsoft article 925681 documents this
issue and provides a fix.
After installing the virtual com port, the correct modem driver may be installed to the com port (for the USB versions, make sure
the USB port of the Cell is connected with a SIM card before the modem driver is installed).
