I have a USB keyboard and mouse (running through a KVM) and if I try to use an external USB hard-drive or a USB pen-drive I encounter this same problem. The keyboard and mouse stop responding. The USB hard-drive or pen-drive also stops working. Pen-drives are almost always readable and sometimes writeable. Hard-drives are sometimes readable but never writeable.

I've tried hooking things up through hubs and I've used different motherboard ports and tried other cables and it makes no difference. Have also tried multiple USB devices and it again makes no difference. All these devices work without problem on other systems.

If I login to the system remotely and do:

   rmmod ehci_hcd
   sleep 3
   modprobe ehci_hcd

the keyboard and mouse will work once again.

I tried booting the latest Ubuntu 8.10 LiveCD beta (via a USB CD-Drive), which supposedly has kernel 2.6.27 and that failed also.

My error logs are similar to the ones others have posted but I can post some if it would help.

My system is:
