Could you explain more details about the issue?

- changeset of xen/kernel, arch (x86 or x64)
- H/W (CPU, M/B, USB Host controller, ...)
- USB device (Device name and VendorId/ProdId)
- your setting (show me xenstore entries)

Failure of the SCSI-device scanning did not occur with the storage
devices that I've tested.

But, this error might happen due to the mismatch of the
urb->transfer_flags.
I've seen this in the very early version of pvusb.
