Hi Jack,
you have the device in the correct driver now and you have got rid of
the legal disclaimer but there is still a problem with the patch.
Interface #1 which is for ADB should not be claimed by the option
driver, you have to add a line blacklisting (reserving)it.
thanks
Lars

Hi Lars,
Thanks for your review and pointing that out.
I will fix this by changing the entry to use USB_DEVICE_AND_INTERFACE_INFO with RSVD(1) to blacklist interface #1 (ADB).
I'll submit the v2 patch shortly.
Thanks.
