usb device not recognised

[jdbca at clix.pt]

I have a Teclast TL-C300 usb media player which works fine with Slackware 12.2 and Windows XP, but is not properly recognised by 
FreeBSD.
I have other usb devices, eg camera, which all work fine, so I am guessing that my config is OK, although I do see errors with 
these devices too.
According to kerneltrap, another Teclast device needed a patch in Linux to reduced the data transfer block size to make it work, 
so perhaps it needs a quirk for FreeBSD too.
Does anybody have experience of this device or recognise the symptoms?

I am running FreeBSD 7.2 and I am up to date with stable.

I have these entires in the kernel which are probably relevant:-
device          scbus
device          da
device          cd
device          pass
device          ses
device          atapicam
device          uhci
device          ohci
device          ehci
device          usb
device          ugen
device          uhid
device          ukbd
device          ulpt
device          umass
device          ums

If the TL-C300 is present at boot, boot freezes when it probes the device but resumes if the device is removed.

When the TL-C300 is plugged in after boot, it produces the following console report:-

umass1: <RockChip ROCK MP3, class 0/0, rev 2.00/0.00, addr 2> on uhub2

da0: 40.000MB/s transfers
da0: 1900MB (3892224 512 byte sectors: 255H 63S/T 242C)

but fails to create /dev/da0. Also, when it is plugged in, no other usb devices are recognised.

Unplugging produces this:-

umass1: at uhub2 port 2 (addr 2) disconnected
(da0:umass-sim1:1:0:0): Synchronize cache failed, status == 0x39, scsi status == 0x0
(da0:umass-sim1:1:0:0): lost device
(da0:umass-sim1:1:0:0): removing device entry
umass1: detached

By contrast, when I plug in the camera, I get this report which also contains errors, but it does create the /dev entries and is 
mountable:-

umass1: <DV USB Device, class 0/0, rev 1.10/1.00, addr 2> on uhub0

unplug camera:-

(da0:umass-sim1:1:0:0): lost device
(da0:umass-sim1:1:0:0): removing device entry
