Comment 18 for bug 1103164

The usb hw works well, mean no need to physically reconnect it (it was critical issue).
However there are still kernel messages "can't reset device, 0000:00:1a.0-1.3.4/input0, status -71" (minor).

So for me currently it is ok.

-------------------------------
For n0PxN0p I would recommend to check the issue with latest ubuntu kernel (hopefully it should be ok with ubuntu 13.04)
