The vendor (0x0d7d) identifies the manufacturer as Apacer. When I plug it in, it does not work. I get the following messages: umass0: USB DISK 2.0, rev 1.10/0.50, addr 2, SCSI over Bulk-Only umass0:0:0:-1: Attached to scbus0 as device 0 (da0:umass-sim0:0:0:0): got CAM status 0x4 (da0:umass-sim0:0:0:0): fatal error, failed to attach to device (da0:umass-sim0:0:0:0): lost device (da0:umass-sim0:0:0:0): removing device entry $ usbdevs -v hburch-lap:~/kern-save $ cat /tmp/devs Controller /dev/usb0: addr 1: self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00 port 1 addr 2: power 500 mA, config 1, USB DISK 2.0(0x1300), (0x0d7d), rev 0.50 port 2 powered PRs on same device: kern/43627 and kern/50297 >How-To-Repeat: Buy device, plug in, and hope version matches. >Fix: The problem appears to be that umass_match_proto is noticing that bInterfaceProtocol is UIPROTO_MASS_BBB, and decides that it's a ZIP drive. I can fix this by commenting out lines 736 and 739 (about) of umass.c, so that the case reads: case UIPROTO_MASS_BBB: /* sc->drive = ZIP_100; */ sc->proto |= UMASS_PROTO_BBB; sc->transfer_speed = UMASS_ZIP100_TRANSFER_SPEED; /* sc->quirks |= NO_TEST_UNIT_READY; */ break; However, this is clearly the wrong way to fix this. The proper fix is not clear to me. This fix makes the device work. However, when I unplug it after running, I get: umass0: Phase Error, residue = 0 (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 Although this error does not appear to be causing functional issues, this is fixable by adding the following quirk to cam/scsi_da.c: { /* * Apacer USB drive */ {T_DIRECT, SIP_MEDIA_REMOVABLE, "", "USB DISK 2.0", "*"}, /*quirks*/ DA_Q_NO_SYNC_CACHE }, The empty vendor will be the subject of other PRs, as it's fix is two changes unrelated to this issue. >Release-Note: >Audit-Trail: >Unformatted:
