I have an Intel Pocket PC Camera. It shows that it is installed and I could send a video e-mail but when I went back to send another one - no video. I checked trouble shooting from their site. Find that there are two files missing. USBINTEL.SYS and USBHUBD.SYS I can't find these files using SFC or on my installation disc. Help!!!! I don't know where to go for help. The video will not work without these files. Any help will be appreciated.
