removable usb media don't present devices to mount

    I'm using FreeBSD 6.0-rc1, and I'm having trouble with removable usb memory
    drives. I plug the device in, and get this from dmesg:

    umass0: LEXAR MEDIA JUMPDRIVE2, rev 2.00/1.25, addr 2

    There is no mention at all of /dev/da0, which is, as I understand it, the
    device that is traditionally presented to mount. usbdevs sees the device,
    and gives this output.

    port 8 addr 2: high speed, power 70 mA, config 1, JUMPDRIVE2(0xa300), LEXAR
    MEDIA(0x05dc), rev 1.25

    This occurs both with GENERIC kernels, and a custom kernel that I configured.
    The custom configuration is listed here:

    Other things of interest. At random intervals, unplugging the device and
    replugging it gives me this out of dmesg:

    umass0: LEXAR MEDIA JUMPDRIVE2, rev 2.00/1.25, addr 2
    da0 at umass-sim0 bus 0 target 0 lun 0
    da0: <Generic STORAGE DEVICE 1.25> Removable Direct Access SCSI-0 device
    da0: 40.000MB/s transfers
    da0: 250MB (512000 512 byte sectors: 64H 32S/T 250C)
    (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x10, scsi status
    == 0x0

    However, the mount command hangs in this case (I left it, and came back an
    hour later and it hadn't mounted).

    The USB drive works, as it is autodetected and mounted by Mac's and various
    other USB memory drives are not properly recognized either.

    On a whim, I booted into a FreeSBIE live CD that I have, and it was
    automounted and functioned correctly.

    One last little bit of interest, booting hangs immediately before attempting
    to mount / if I boot with the device plugged in. Booting continues normally
    when I unplug the device. I am not sure if this is significant.

    I would appreciate any help that could be offered. Thanks.
