Prior to these changes I successfully used my USB wireless adaptor, 2gig USB storage device, and my 500 gig Seagate freeagent backup drive. With few issues. (Although vista sometimes got moody if I unplug them without stopping them which is fair enough hehe.
Since this happened I have not been able to use any of the USB ports. When I plug the device in either nothing at all happens or I get windows searching for a device driver before not recognising the device (the hard drive being the most important to me ) and then showing as unknown device. Various possible solutions to this possibly widespread problem are shown on the web.
1. USB power. For USB powered devices there is apparently a power issue from USB ports and particular cabling adaptors exist to resolve this. However my device is mains powered directly from the socket.
2. Issues are shown with specific files in the INFCACHE file. I have tried these fixes. ie changed permissions on this file and deleted it. No change there.
3. Checking device manager for exclamation marks etc or dubious looking USB hub entries. Non shown. Tried deleting the current hubs and allowing windows to reinstall. Still nothing.
4. Downloaded and flashed the latest BIOS for my motherboard. EVGA X58 Tri SLI. Some nice new features but no change to my problem.
5. Downloaded and installed the latest chipset drivers from the EVGA website.
Basically I am completely stuck and can think of no other possible solutions. Double and triple checked the bios settings and reset the BIOS to default to see if it would make any difference. No change.
Does anyone at all have an idea what I can do. I have masses and masses of info I need to access from applications on my pc which reside on the USB drive. Worst case scenario I will build another machine and see if it will read the drive but that seems like using a shotgun to crack a walnut. I also really do need to be able to utilise USB devices on this pc in general. HELP Please if you can. ) hehe many thanks.
