No response from usb_at_ so hopefully someone (julian) will respond here

Hi all,

I have a new 1GB JetFlash TS1GJF2B 2.00 thumb drive.

When I plug in the thumb drive dmesg(8) outputs the following:

    umass0: USB Flash Disk, rev 2.00/2.00, addr 2

# mount -t msdos /dev/da0 /mnt
msdosfs: /dev/da0: Resource temporarily unavailable

and then after trying to mount I get these errors in dmesg(8)

    fsync: giving up on dirty: 0xc2c24420: tag devfs, type VCHR, usecount
    1, writecount 0, refcount 33, flags (VV_OBJBUF), lock type devfs: EXCL
    (count 1) by thread 0xc309c320 (pid 9693)
            dev da0

I have the following in my kernel:

device          ehci            # Enchanced Host Controller Int
device          uhci            # UHCI PCI->USB interface
device          ohci            # OHCI PCI->USB interface

OS: FreeBSD 5.3-STABLE #21: Thu Jan  6 16:45:52 CST 2005

Not sure what to make of this. Anyone ?
