dmesg and usb register dumps

Tested four configurations with kernel 2.6.27.5:

1 - With ATEN KVM. Fails as before: can't complete write to USB HD
    and keyboard communication is lost. (dump withkvm)

2 - ATEN KVM unplugged. KBD and USB HD plugged into a DLink hub.
    This *fails* also: can't complete write to USB HD and keyboard
    communication is lost. (dump withdlink)

3 - ATEN KVM unplugged. KBD plugged into DLink hub, HD plugged into MBD.
    This works but it looks like (if I'm understanding the log messages)
    that it was still losing communications with the keyboard, although
    the keyboard continued to work. (dump withdlink-kbd)

4 - ATEN KVM unplugged. KBD plugged MBD, HD plugged into DLink hub.
    This works: write completes, KBD continues to work. (dump withdlink-hd)

Note that the garbage output characters during boot seem to have gone away with the new kernel.
