Description of problem:
While copying a large tarball from external USB harddrive (2.5" enclosure), the device disconnected and the whole USB stopped working, including the mouse.
There was no reaction whatsoever when reconnecting the USB devices, I had to reboot to make them working again.

Version-Release number of selected component (if applicable):
Fedora 15, KDE, all updates installed.

How reproducible:
it did not happen the second time.


Steps to Reproduce:
1. Plug in the external harddrive
2. Copy a file to internal drive
3. boom
  
Actual results:
file transfer broken, usb stopped working

Expected results:
file trasfers ok, usb still works

Additional info:

This is on a Toshiba Tecra M11.
I've never had issues with the drive on the machine when using it under Solaris.
