Hello,

This patch solves problems with one of my memory sticks:

http://lists.freebsd.org/pipermail/freebsd-arm/2007-August/000704.html

Now:

umass0: <Corsair Flash Voyager, class 0/0, rev 2.00/11.00, addr 2> on uhub0
umass0: SCSI over Bulk-Only; quirks = 0x0000
umass0:0:0:-1: Attached to scbus0
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Corsair Flash Voyager 1100> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 967MB (1981440 512 byte sectors: 64H 32S/T 967C)

umass0: at uhub0 port 1 (addr 2) disconnected
(da0:umass-sim0:0:0:0): lost device
(da0:umass-sim0:0:0:0): removing device entry
