Dell Optiplex GX110 with the following USB whatnots:
uhci0: <Intel 82801AA (ICH) USB controller> port 0xff80-0xff9f irq 11 at device 31.2 on pci0
usb0: <Intel 82801AA (ICH) USB controller> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
and a Wincan (branded as ``Copera'') 64MB USB pen flash drive. Detected
as:
umass0: Wincan USB HDD, rev 1.00/1.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Wincan HARD DRIVE DISK 1.05> Removable Direct Access SCSI-0 device
da0: 650KB/s transfers
da0: 62MB (128000 512 byte sectors: 64H 32S/T 62C)
Using the usb and umass kernel modules from RELENG_4_5.
>Description:
The USB drive is detected, as above, but any attempt to access da0
fails with:
/kernel: (da0:umass-sim0:0:0:0): READ(06). CDB: 8 0 0 0 1 0
/kernel: (da0:umass-sim0:0:0:0): ILLEGAL REQUEST asc:20,0
/kernel: (da0:umass-sim0:0:0:0): Invalid command operation code
/kernel: da0: reading primary partition table: error reading fsbn 0
>How-To-Repeat:
Connect pen drive and try ``disklabel /dev/da0''.
>Fix:
A patch to /usr/src/sys/cam/scsi/scsi_da.c to add a quirk for this
device is below. It works for me on RELENG_4_5. The patch is against
scsi_da.c with RCS Id:
