hi, on recent kernels (3.0.17, 3.1.9, 3.2.1, mainline) i can't transfer files from my mobile via usb-3 port (on usb-2 port it works fine). here's a log starting from device connect.

Created attachment 72280 [details] dmesg output I think this is a similar problem on a ASUS M5A97 pro and an external 1TB USB3 hardrive.
All USB bugs should be sent to the linux-usb@vger.kernel.org mailing list, and not entered into bugzilla. Please bring this issue up there, if it is still a problem in the latest kernel release.
Is this generally true of bugzilla.kernel.org (ie nobody should use it to report bugs), or just for USB bugs?
For USB bugs specifically, other kernel development groups do use bugzilla, it depends on the developers.
