Athlon 64 3200+
80GB / 160GB SATA
ATI AIW 9800 SE
XP Home SP2
After seeming to work fine I now have totally failed USB interface.
On plugging any USB device in (tried simple Flash Memory, Saitek Evo Joystick and HP PSC 1205 printer/scanner), the system goes through the process of recognising that something has been plugged in but then fails to determine exactly what that something is. System Tray pops up messages which finish with "Unknown Device" and then "New Hardware Ready to Use". If, after a suitable pause, I plug the same device in again the System Tray message is "Device Not Recognised". Device Manager does not show any problems except reporting the Unknown Device when it is plugged in.
I have followed some of the Troubleshooting advice which seems to make the most sense including uninstalling all USB Hub Devices and then all USB Controllers. I have also checked that the Flash Memory and Joystick are recognised on ANO machine with no problems. I have tried to update Hub and Controller device drivers (asking it to go to Microsoft to check for latest). From what I can tell the Motherboard drivers are all OK although this is the point at which my knowledge and confidence evaporates!
By way of possibly relevant further background. This PC has been repaired twice - both time with problems related to the motherboard and/or power. I would like to go back to the manufacturer again but it came from Microland Technology ( say no more / take a look at "Is Microland Technology Bust" thread)
Does anybody have any clues?
Should I just get a PCI USB card? (If so any recommendations?) - I say this because in some of the digging I have done so far there seem to be some concerns expressed about on-board USB / Power issues / AMD / VIA chipsets.
Many Thanks,
Neil
