[ale] USB reset error in dmesg

[Rich Faulkner]

Attaching a PS/2 mouse and keyboard resolve the error but by only
removing the device(s) that are causing the problem.  That is not a
solution as all USB have to be working.  I have recommended that the OS
be migrated to 6.x but don't know that this will be accepted.  Another
find was setting the BIOS to support multi-monitor mode (an interesting
connection); the error is not induced.  Only in single-monitor mode does
the USB mouse/keyboard go bugger.  So there is a BIOS connection here
for resource allocation that interacts with EHCI driver (or USB driver)
and the function of low-speed USB device(s).  

In the end, the mouse and keyboard are constantly powering-up and down.
Looks like they fail and reinitialize; then fail; then initialize.  Up,
down, up down...sand-a-floor; side-to-side...you get my drift...
