For some time now I notice these messages when I use my SCSI
tape:
	kernel: usb-uhci.c: interrupt, status 28, frame# 1015
with different frame# each time.

I used a USB mass-storage device a while back, for a short time,
it was since removed.

I am chasing some data corruption and will suspect everything
at this point. Any chance that this causes a problem for scsi
devices?

Anyway, I am rather sure that the usb system should keep quiet
as it is not accessed at all.
