Wireless USB mouse and keyboard only works through USB hub in WinXP

[daukakk]

For several years I have had no problems with my Wireless mouse and
keyboard, with the receiver attached to a powered 7-port USB Hub.

However, recently I recently had to reinstall my PC, still with my
mouse and keyboard well functioning in the same setup.

However, to trace down a mysterious "USB Device" that appears under
"Other Devices" in Device Manager, for which WinXP Pro is unable to
install the drivers, I decided to try to disconnect USB device by
device to figure what this mysterious "USB Device" actually is.
When I disconnected the USB Hub, and attached the Wireless Receiver
directly to the motherboard's USB ports, they stop functioning! I have
tried to reconnect the mouse and keyboard to the receiver, having no
luck. (When booting Win XP that is, the keyboard works fine before
entering WinXP, I can for instance break into BIOS and navigate there
using the keyboard)

(When I return to the original setup (through the USB hub) everything
works fine).

Any theories what is going on here??!??

My MB is Asus M2N-E

Actually, I also have a problem if I attach the USB hub to another USB
port. Is the USB based wireless receiver "sticky" to a particular USB
port, or what?!?

USB drives you nuts sometimes.

(Connecting the USB receiver directly to the same port as connecting
through the USB hub does not work either)

Since you re-installed the XP, did you also reinstall the motherboard chipset
drivers and/or any additional motherboard USB driver? Look on Asus for these.

Yes, I installed the motherboard chipset drivers. However, for USB the
motherboard driver CD explicitly states that the USB2.0 drivers are
included in Win XP SP2 and no special M2N-E drivers are installed in
that respect.
