Further to this, I tested with 2.6.17-rc6-mm2 today, no changes. I've 
attached as .txt files the following;

lsusb output for both a 2.6.16 kernel and the 2.6.17-rc6-mm2 kernel
/proc/bus/usb/devices output, again for the same kernels.

Noting that there are a lot less devices in the -mm kernel due to the 
error below.

Again, any further debugging I can provide, just let me know!

:)J

Please advise
