I am writing my problem in my mother's behalf.
She owns an Acer Aspire 5100, 1GB RAM, 300GB WD HDD, ATI RADEON XPRESS (200M) laptop.
The problem is that I browsed the internet for this problem weeks now, and I haven't found a solution that would actually work.
USB drives gone nuts suddenly one day. Mice and laptop cooler work perfectly, but the thumb drives don't.
A message appears after plugging a USB flash drive that the device is not recognisable by Windows and that drivers should be installed. I chose the automatic driver find, nothing popped up; only that there are no drivers for this device and that it won't work properly.
I thought that if I go to DevManager and delete the USB ports from the list and reboot would fix it, but it didnt.
We tried many flash drives, and only one can be read. And that one, still appears with the window that recommends drivers, but it works properly.
There are 3 ports on the laptop, we swapped USB flash drives to all of the ports, nothing happened, same message appears.
We scanned with MBAM, Avast!, had a registry fix with Registry Mechanic, nothing worked.
Do you have any ideas on the problem?
Thank you for your time.
