Entrega Technologies produced a USB to SCSI converter (model U1-SC25). Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the earlier Entrega product. It uses the Shuttle Technology EUSB-01/EUSB-S1 chips. As with other Shuttle- based converters, a quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with ID 0 can be used. My Xircom PortGear PGSCSI has USB ID 1645:0007. From lsusb output for my unit: iManufacturer 1 Entrega Technologies Inc. iProduct 2 Entrega USB to SCSI Converter There seems to be some confusion about USB VID 0x1645. From reading https://usb-ids.gowdy.us/read/UD/1645 it seems the VID assigned for Entrega was 0x66D (= 1645 decimal). However (all?) Entrega devices use VID 0x1645, which was actually assigned to Cross Match Technologies GmbH! This patch only adds a quirk for 1645:0007. However the Windows driver .INF file contains three USB IDs: 1645:0007 "PortGear USB to SCSI Converter" 085A:0028 "PortGear USB to SCSI Converter" 085A:0032 "PortStation SCSI Module" Thus it's possible that later PGSCSI converters used ID 085A:0028 instead. I can submit a patch for that too, or would someone need to confirm that it actually exists in the wild first? I couldn't find any mention of the PortStation SCSI Module on the web; perhaps it was cancelled before release.
