Good Folk:
I think we can close the book on this. Today, all of the USB ports on one
just stopped working altogether for anything, not even a little mouse when
plugging in gives any result. The second one is now reliably showing in
dmesg that it is running full-speed not high speed. So, it's h/w

using OpenFirmware or Linux? I'm expecting you used Linux.
We made some USB changes in OpenFirmware, but these ought not to have
had this effect, and should have n
