Subject: usb error messages

I use 2.6.19.1 kernel on the laptop 'compaq nc6320'. While booting the
kernel, I see  the following error:
  usb 1-1: device not accepting address 2, error -71

Assuming that this 1-1 means bus and device id, this appears to be the
UHCI controller. I noticed that this error has been reported by people
in the past, but the possible reasons listed doesn't seem to be the
root cause here.

If I just restart the machine instead of shutdown, I see one more usb error:
  usb 5-1.2: device descriptor read/64, error -32

which would appear like some reset/close operation wasn't done in the restart.

Is there some way to debug and isolate these problems further? The
'suspend-to-disk' (using 'swsusp'/'software suspend 2') are not
working on this laptop and I am thinking these errors might be
contributing to the problem.

Thanks for any help.

I have attached the 'lsusb -v' output.
