Re: WUDFRd.sys is not present - win XP

Would you mind using your real name instead of “My RAC Account”?

One Quick question. I tried to install the umdf fx2 sample
driver by plugging in the osr fx2 usb device to learn the code flow.
As I said earlier, its failing. Do we need to change the vid/pid and
new GUID for this device too in inf file?

Unless I am mistaken, the VID/PID in the INF file in the osrusbfx2/umdf
samples matches the OSR FX2 device (045E/94AA). You can check that
yourself. Go into Device Manager, find the device (it probably has a
yellow bang), double click, go to Details, and look at the Hardware ID.
You should see VID_xxxx&PID_xxxx in there.

You will probably want your own GUID, just so there is never any
confusion, especially if this will ever be used outside your own
computer. After all, GUIDs don’t cost anything.
