Sometime between 2.5.69-bk4 and 2.5.69-bk8, something with related to 
the USB was messed up. I get the below lines in my dmesg.
hub 2-0:0: new USB device on port 1, assigned address 2
usb 2-1: USB device not accepting new address=2 (error=-110)
hub 2-0:0: new USB device on port 1, assigned address 3
usb 2-1: USB device not accepting new address=3 (error=-110)

The first device is my Logitech Cordless Optical Trackball.
The second device is my TI USB Graphlink.

The Trackball still works. Not sure about the graphlink as I don't have 
the software installed yet. :-/
I used the same config for bk4 as I did for bk8. It've attached my 
config for bk9 since it is the same anyway.

Thanks,
David
