Installing the USB Modem Driver

This section assumes you are familiar with installing and configuring a modem under
Windows 2000 and Windows XP. As both operating systems use multiple methods to access
modem settings this section provides only a brief summary of the most important steps.
Take care that the "usbmodem.inf" file delivered with TC65 is at hand. Connect the USB
cable to the TC65 host application (for example the evaluation board DSB75) and the PC.
Windows detects TC65 as a new USB modem, opens the Found New Hardware Wizard and
reports that it is searching for the "Siemens AG WM USB Modem" driver. Follow the
instructions on the screen and specify the path where the "usbmodem.inf" file is located.
Windows will copy the required software to your computer and configure the modem by
assigning a free COM port. If you are already using more than one COM port then the next
free one will be allocated. Click Finish to complete the installation.
Notes for Windows 2000 only:
•
During the installation procedure you will be prompted for the "usbser.sys" driver. Make
sure the file is present before you start installing the above inf file.
The "usbser.sys" file is not delivered as a single file, but must be extracted from a
Windows 2000 cabinet file. This is either the file "driver.cab" located in the "I386" folder of
the original Windows 2000 CD or a later cabinet file inside the Service Pack. SP4 for
example includes the "sp4.cab" file which can be found in its "I386" folder. The
"usbser.sys" driver from the Service Pack has priority over one provided with the
standard Windows 2000 install CD.
•
It is necessary to restart Windows 2000 to make the changes take effect.
