Dear friends, In my job one PC does not recognizes any pendrives, there is installed win 7, all drivers are correct, all that files: - usb.inf - usb2.inf - usbport.inf - usbprint.inf - usbstor.inf - usbvideo.inf are in C:\Windows\inf folder what is problem? how to correct that problem? thanks.
sometimes there is issue with how devices are seen.. MTP media device listed in device manager? usbstor.sys missing ? or the .inf bios settings ?
Question is: Could he run any USB drive on that machine: Yes or No? If he can, that USB is installed correctly!
No he can't run any usb drive. also canon scanner not recognized, drivers was installed of canon but didn't.
If USB isn't Admin locked, in that case it looks more like an hardware(MB) problem As you wrote PC, it seems to be an Desktop. If so and you have an PCI USB Card, I would place that in the MB and test USB will work using that Card.
Yes. it's the Motherboard. Able to repair? Maybe yes and no. It's depend on what service is available. We've quite good services in Bangkok. Anyway, it's depend, if there is an hardware problem, what exactly it is. Not everything could be repaired or repair is simply to expensive! As I wrote in my last post, look to check with an PCI USB 2 or even 3.0 Card that those will work. An PCI USB 2 Card cost in Bangkok 5 bucks!
