View Single Post - Strange USB problem...

Spire · Rated XXX

I have issues with the NF3/NF4 chipsets and USB.

I am running an IOGear USB KVM and my MX700/Elite Keyboard setup.

On any chipset other than the above mentioned, everything works great, plug and play. On the Nforce chipsets, the mouse/kb is detected and installation goes fine, but I get only scattered mouse movements.

If I roll the mouse around, I get a random cursor movement every 30 seconds or so. The same with the keyboard.

If I bypass the KVM, the Elite setup works fine by itself.

This has been the same on the two Nforce 3 based MSI NEO boards and the Nforce 4 DFI board. My older Nforce2 DFI works no problem.

I have changed the USB jumper from +5v to +5VSB and it did not help. Installing the USB 2.0 driver did not help.

Any suggestions? (Besides get rid of KVM)
