Comment 26 for bug 986817

I'm seeing the same problem with my UA-1000 (which uses the UA-101 driver). I think the OP has covered all the bases, but I'm pasting the lsusb -vvvv for this device since it is a different model number. Let me know if you want any other info.

mint@mint ~ $ sudo lsusb -s 1:2 -vvvv
