Hey guys, a customer of mine came to me with a pc that claimed to be not working with usb.
it had some other probs with HD partitions but that's not relevant imo.
tried it with their USB flash drives, their Digital Camera and PSP and i only get "USB device not recognized", "Unknown Device" and "No Driver Installed", that classic problem... you know what i mean.
my first diagnostic was "ok, your products are no good" so i tried it on other pc's and i get the same result.
tried with my USB drive, which i checked before and it used to work.
and after inserting it into their computer, my usb device started to get the same thing! on any pc!!!
and also with another flash drive i tried.
so conclusion is that this pc kills usb devices. tried to rescue them with no real solution.
any ideas what parts should i check?
Power issue on the USB, probably should replace the motherboard. The motherboard delivers power for the USB, as well as onboard fan headers. The PSU is likely not to blame if the system ran fine otherwise.
