I have been running my custom built Vista Ultimate 32bit computer for some time now with no problems.
I just recently installed an additional 2Gig of RAM (now have 4Gig). Everything seemed fine for some time, then I got an error:
I checked the device manager and noticed several 'Unknown Device' listed. I also checked the USB Hubs and noticed that some of them listed an 'Unknown Device' attached to the hub when there were none!
I removed ALL USB devices and still have the same problem. The only way I can solve it is to disable the USB in the BIOS, which really does NOT solve the problem as I no longer have USB support.
While reaserching this issue I have updated ALL drivers, installed ALL windows updates, and I have even deleted all the USB hubs and 'Unknown Devices', rebooted adn they all came back!
It seems there was a thread somewhere that mentioned Windows Vista machines with greater than 2Gig of RAM haveing this problem but I can NOT find a fix!
Can you offer me any help, or do I just have to remove my extra RAM until Microsoft corrects the problem?
Thanx in advance,
