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
umass0: detached


Best Regards

All,

The attached patch should make CAM behave properly with regard to
probing device serial numbers only when the device advertises that
it supports it. It will hopefully eliminate the need for the
CAM_QUIRK_NOSERIAL quirk (one instance is left because of an unrelated
legacy problem that may or may not be possible to fix). This should
especially benefit USB-UMASS devices, where the console output should
be less noisy. It might even make more devices work out-of-the-box.
So please focus testing on USB, but I'd also ask that people test
the following devices as well as any firewire devices:

* Western Digital My Book 250GB (USB)
* Maxtor Personal Storage 3000XT (Firewire)

Thanks,

Scott
