Leadtek DTV 2000DS Not Working in Mythbuntu 11.04

I'm running Mythbuntu 11.04 (2.6.38-11 kernel) and recently bought a Leadtek Winfast DTV2000DS PCI dual tuner card. It's supposed to work out-of-the-box but mine just doesn't... I've tried the card in a Windows 7 Media PC and it worked sweet as, so I know there's nothing wrong with the hardware...

So the relevant section from lsusb is

$lsusb
/
Bus 006 Device 002: ID 0413:6a04 Leadtek Research, Inc./

and with more detail

$sudo lsusb -v -s 006:002

The relevant section from dmesg is

$dmesg

if i try and manually load the driver i get

$sudo modprobe dvb-usb-af9015

$ dmesg

/[ 6163.061092] usb 6-1: usbfs: USBDEVFS_CONTROL failed cmd lsusb rqt 128 rq 6 len 255 ret -110/

I've messed around a lot, different versions of the firmware etc, i chucked in an empty HDD and tried a clean install of 11.04, and tried to install 11.10 Beta 1 (that doesn't work - it freezes after the Remote Control Setup page as someone reported here https://bugs.launchpad.net/bugs/854426), and nothing has worked besides using it in a Windows machine.

Any ideas?

cheers
