This should be easy enough, by adding an extra check to storage_probe(). If id doesn't lie between the start and end of usb_storage_usb_ids then it must come from a dynamic ID. In that case, pass usb_stor_probe1() a fixed usb_device_id entry that describes a device using the Bulk-Only transport with the Transparent SCSI protocol. The various subdrivers, like alauda, datafab, and so on, probably should have their no_dynamic_id flags set. They could be fixed up in the same way, but it would be a lot of work with very little gain.
