Ming Lei,

those two links don't provide any detailed report whatsoever. Looking at 

	https://bugs.launchpad.net/ubuntu/+source/linux/+bug/913164

there seems to be quite some discussion, but covering multiple models from 
multiple vendors (and likely multiple different patches needed).

So if there are patches that need to be applied (likely device ID 
additions as far as I understand this monster launchpad bug entry), please 
point me directly to the respective patches or send me a little bit more 
details (VID/PID/protocol needed), and I'll queue the patches.

Thanks,
