USB Virtual COM Port Installation For Windows XP
The USB in BlueBoard might not get enumerated if it does not find the appropriate driver for it.
To check USB enumeration status Right Click on “My Computer” icon and select Manage. A “Computer
Management” window opens. In this select Device Manager as shown below:
The device uses the
usbser.sys
driver. This driver file is not unpacked in Windows by default and needs
to be extracted from a Windows .cab file which should be in the C:\WINDOWS\Driver Cache\i386
directory for Windows XP SP2. Change directory to
C:\WINDOWS\Driver Cache\i386
expand the
CAB file by running the below command in Command-Prompt
expand sp2.cab -f:usbser.sys C:\WINDOWS\system32\drivers
Note: On some systems like the XP home edition; extraction of driver files from cab files might not be
supported. In such situation the user can download the usbser.sys file from
http://blueboard-
lpc214x.googlecode.com/files/usbser.sys
and copy it to C:\WINDOWS\system32\drivers folder
