same problem on acer 5050 3371 , maybe the the problem is we been hack.
I have an Acer Aspire 3100 Notebook. A month or so ago it shut itself down and had a heck of a time restarting. At some point it corrected itself and now runs perfect.
Problem: since this incident, I no longer have the use of my USB ports.
If I plug in a mouse, mp3 player, card reader, etc.. they are obviously getting power, but the drive letters do not show in Windows Explorer, nor -in the case of the mouse- is there any input from the device itself.
Device manager of course, says all drivers are fine, but I updated and replaced them all anyway.
I have uninstalled USB controllers and rebooted to let them reinstall, but still nothing on the ports is working.
Can anyone suggest what the solution may be?
The only possible 'glitch' I can find is that the driver for the
PCI IDE Controller -ATI 4379 Serial ATA Controller - will not install properly. When trying to install, it says the "name is already in use"
Any help would certainly be much appreciated!
