I have a nice working bridge, in a no-name 2.5" disk-enclosure: $ lsusb Bus 005 Device 007: ID 04b4:6830 Cypress Semiconductor Corp. USB-2.0 IDE Adapter $ scsi_id -x -g -p0x80 -s/block/sdb -d/dev/sdb ID_VENDOR=TOSHIBA ID_MODEL=MK1017GAP ID_REVISION=0000 ID_SERIAL=STOSHIBA_MK1017GAP_144M6603 ID_SERIAL_SHORT=144M6603 ID_TYPE=disk ID_BUS=scsi $ /lib/udev/usb_id -x /block/sdb ID_VENDOR=TOSHIBA ID_MODEL=MK1017GAP ID_REVISION=0000 ID_SERIAL=TOSHIBA_MK1017GAP_DEF107727402 ID_TYPE=disk ID_BUS=usb Another one just shows for exactly the same disk put behind the bridge: $ lsusb Bus 005 Device 012: ID 0402:5621 ALi Corp.
