USB devices not displayed

[hans_nl]

Hi, I hope this the right place for this topic. My problem is that devices connected to my PC through USB are not dislayed anywhere, neither in the device manager, nor in Explorer and "My computer" (only a listing of USB controllers in the device manager). Connected hardware communicates however with the PC as it should. In the past this was no problem. I don't know what has changed. The OS is Windows XP Home Edition SP2; the motherboard is an ASUS P4PE-X/SE with BIOS version 7.07.01. Can anybody help me out?

This sounds like they weren't properly dis-connected using the USB device manager in the system tray...

Here's what you can try though.
Dis-connect all USB devices and do 2 clean boots and power down.
Re-boot and go to Control Panel / System / Hardware / Device Manager.
Find all instances of USB, right clik them and select remove.
You will get a warning message...ignore it.
Shut down and re-boot.
After completing startup power down the machine again.
Re-connect the USB devices ONE AT A TIME and power up and repeat the shutdown power up sequence for each device...

Let us know how this goes.

Patio, thanks for the advice. I think I have everything working again.

Excellent, we love success stories here...stop by anytime.

Also if you are running an external HDD on that machine go back to Control Panel / System / Hardware / Device Manager.

Right clik on all the USB hubs and select Properties. Under the Power Tab turn off "Let Windows turn off this device to save power"...

It is a default setting in Windows and should not be on. Period.
