Julius, I tested the patch on kernel 3.2.61, on two USB 3.0 host controllers (Asmedia and NEC), and four USB 3.0 devices (three of which were previously triggering the issue, and one worked fine). On the Asmedia controller, the patch fixes the regression, but with one of the devices (Areca ARC-5040) I still occasionally get the following messages in the log: Jul 15 12:34:50 ubuntu kernel: [ 1855.902804] usb 4-1: reset SuperSpeed USB device number 2 using xhci_hcd Jul 15 12:34:50 ubuntu kernel: [ 1855.920190] xhci_hcd 0000:03:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff880423628480 Jul 15 12:34:50 ubuntu kernel: [ 1855.920197] xhci_hcd 0000:03:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff8804236284c0 These messages appear out of nowhere, seemingly without any cause, usually some time after the device has been plugged in (time varies from 30 sec to 30 min). This worries me a little, because these exact messages were one of the symptoms of the regression. However, the device seems to work fine and remains accessible. Without your patch, such messages were logged every 30 seconds, and the device was not accessible until they stopped. I did not notice any problems with other devices on the Asmedia controller (with the patch), nor with any devices on the NEC controller (with or without the patch). I have not yet tested any other kernel version; I intend to compile and test the newest available kernel tomorrow. Where should I add the "Tested-by" tag? > The patch is up here, I think you should've been CCed on it Indeed I was, the mail got misplaced among other linux-usb messages. Sorry about the confusion.
