Open System Information (MSINFO32.EXE) and navigate to Hardware Resources > IRQs. Click anywhere in the right pane and then press CTRL-A and then CTRL-C. You have copied that data to the clipboard. Paste that data in a reply here.
Upgrading an OS rarely goes without a hitch. If you installed the 4in1 drivers, you should see VIA host controllers in Device Manager. Try upgrading the driver(s) manually.
The beauty of Win2K is that you can reinstall the OS without losing your data. Formatting is not necessary.
Unplug all USB devices, boot from the CD and select Repair > Fast Repair. Apply the 4in1s first and then SP3. Test USB.
If it fails, leave ACPI enabled and boot from the CD again. Reinstall to the same partition. Setup will remove the first WinK and install fresh. You'll have to reinstall programs because they won't be registered anymore.
: I have been experiencing problems with my USB ports sinc upgrading to Windows 2000 professional, with Office XP.
: The computer (running on standard universal pci to usb host controllers) does not recognise any device plugged into them, although it does not report any sort of error message. The USB drivers are present and according to device manager, working properly. I am trying to connect a canonscan D1250u2 scanner, but a USB headset gave the same result. Uninstalling the drivers for the scanner and reinstalling them does not work. I can not install a twain driver.
: In the Resource Base it says usb devices prefer IRQ 9, yet on my list, both ports have been allocated to IRQ 11, along with my Ethernet networking card. Is the ethernet card overriding the USB device? If so,can I reallocate IRQs in Windows 2000? MS seems to suggest this is not possible.
: I visited the Jetway site(makers of my motherboard), but there was nothing relating to this problem. I am wary of flashing my system with a useless and potentially damaging bios 'upgrade'. The ACPI function on my computer was set to Neutral on upgrading. I have enabled it in bios set-up with no discernable effect.
: In my bios set-up there is an option for Modem Allocated To:, which is set to IRQ3. The modem to which it refers, A ADR Voice Modem, has been uninstalled along with its drivers, when I upgraded to an ASDL server (via Novell netware).
: Please help if you can!
