Hi,

   I'm running FreeBSD 10.0 r226042 on AMD64 and I'm having problems
with the following device:

        umass0: <Kingston DataTraveler 200, class 0/0, rev 2.00/1.10,
addr 7> on usbus0
        umass0:  SCSI over Bulk-Only; quirks = 0x4001
        umass0: Get Max Lun not supported (USB_ERR_TIMEOUT)
        umass0:5:0:-1: Attached to scbus5

   as you can see, UQ_MSC_NO_GETMAXLUN should be set to use the device.
As it is a 64Gb mass storage I would like  to use it.

   I tried to manually add the quirk and it worked. Later on I tried
with 9.0Beta2/i386 on the same machine and the problem also appeared. So
I made a patch (which works on CURRENT, did not try with STABLE) to add
the quirk, which is attached.

   Hans: is it necessary to fill a PR with the patch or would it be
enough with the inline patch?

   Gus
