Ideally for this task, the USB stack would indeed use the new driver
architecture. Since it doesn't do this, and the driver architecture is
still not at all finished, I would think it might be a good idea to add
support for the old SCSI interface to our SCSI bus manager. I guess
we'll work on that and the new driver architecture on the pre-
BeGeistert coding event in Düsseldorf.

For now, I can only recommend to either add support for the old SCSI
interface to our bus manager, or wait for BeGeistert so that we can
come up with a plan on now the new driver architecture should look
like.
