Go to update driver USB VIDEO etc.. go for the option you have DISK, than make a pause, Run the same driver downloaded for VISTA and wait to hit the next button, then: Go to your temp folder, and search for the last folder created, there you will find the *.INF file. Select it, and Voila!

Temp folder is in: Users/(user)/AppData/Local/Temp/
