Comment 49 for bug 1371233

I was affected by usb3.0 for years. Once Kernel 3.12(test release, linux-headers-3.12.0-031200rc2-generic_3.12.0-031200rc2.201309231935_amd64.deb, etc) has resolved my issue and works for a year, but since I update ubuntu to 15.04, it appears again and again.

I have the phenomenon as link described, http://unix.stackexchange.com/questions/91027/how-to-disable-usb-autosuspend-on-kernel-3-7-10-or-above.
I'm testing #44 suggestion, and I hope it will help me to step out the issue. Thanks, Malachi de AElfweald (malachid)

I will give back the test result tomorrow.
