This is a note to let you know that I have just added a patch titled HID: usbhid: Fix the check for HID_RESET_PENDING in hid_io_error to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.8-ckt8.

It was reported that after 10-20 reboots, a usb keyboard plugged into a docking station would not work unless it was replugged in. Using usbmon, it turns out the interrupt URBs were streaming with callback errors of -71 for some reason. The hid-core.c::hid_io_error was supposed to retry and then reset, but the reset wasn't really happening. The check for HID_NO_BANDWIDTH was inverted. Fix was simple. Tested by reporter and locally by me by unplugging a keyboard halfway until I could recreate a stream of errors but no disconnect.
