USB on Vista


#1

After 4 years or so since my last PC purchase I broke down and bought a PC. Unfortunately, it was nearly impossible to find on without Vista. Since Vista isn’t supported by Wavecom yet this has presented some interesting challenges. I’ve been able to get around most everything with Virtual PC but I needed native Vista USB support since USB doesn’t work with Virtual PC. I’ve put in a support request for USB support on Vista but in the mean time I’ve found an interesting solution.

I found this discussion on USB INF files and Vista:
forum.sparkfun.com/viewtopic.php … 776caa610a

If you download the Microchip driver linked in the discussion:
ww1.microchip.com/downloads/en/D … p_v1.3.exe

Then Modify the INF file from Microchips VID and PID:
[SourceDisksFiles]
[SourceDisksNames]
[DeviceList]
%DESCRIPTION%=DriverInstall, USB\VID_04D8&PID_000A

[DeviceList.NTamd64]
%DESCRIPTION%=DriverInstall, USB\VID_04D8&PID_000A

To Wavecom’s VID and PID:
[DeviceList]
%DESCRIPTION%=DriverInstall, USB\VID_114F&PID_1234

[DeviceList.NTamd64]
%DESCRIPTION%=DriverInstall, USB\VID_114F&PID_1234

I’ve been using PUTTY to communicate over the virtual COM port for a while now without any problems.
