USB_ERR_TIMEOUT and USB_ERR_STALLED

[Mike Tancsa]

I am trying to use RELENG_8 to monitor a number of APC upses and it 
seems when there are more than one, I start to see a lot of USB 
errors with the devices "coming and going"

In the logs, I see a lot of

This is with a kernel from Oct 4th, i386.  Any idea what might be up 
or how to debug this ??  Setting
hw.usb.debug to anything > 0 causes the system to almost hang under 
the load unfortunately.
