usb-storage buffer i/o error


I have a question about usb-storage:

I am running linux-2.6.5-rc3-ben0 on ppc and have a USB storage unit attached
to my USB port. I get the following in /var/log/messages:

Is there something wrong with my hardware? Is there some way to get
the drive working? I have not yet been able to access it.

The drive is a Maxtor DiamondMax Plus 9 (120GB) and is not known to work.

This is the lsusb output:
