2014-11-25T01:01:55Z

This wireless mouse receiver needs a reset-resume quirk to properly come out of reset. BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1165206 Signed-off-by: Hans de Goede Cc: stable Signed-off-by: Greg Kroah-Hartman

usb: xhci: rework root port wake bits if controller isn't allowed to wakeup

2014-11-22T15:34:20Z

When system is being suspended, if host device is not allowed to do wakeup, xhci_suspend() needs to clear all root port wake on bits. Otherwise, some platforms may generate spurious wakeup, even if PCI PME# is disabled. The initial commit ff8cbf250b44 ("xhci: clear root port wake on bits"), which also got into stable, turned out to not work correctly and had to be reverted, and is now rewritten.

USB: xhci: Reset a halted endpoint immediately when we encounter a stall.

2014-11-22T15:34:20Z

If a device is halted and reuturns a STALL, then the halted endpoint needs to be cleared both on the host and device side. The host side halt is cleared by issueing a xhci reset endpoint command. The device side is cleared with a ClearFeature(ENDPOINT_HALT) request, which should be issued by the device driver if a URB reruen -EPIPE. Previously we cleared the host side halt after the device side was cleared. To make sure the host side halt is cleared in time we want to issue the reset endpoint command immedialtely when a STALL status is encountered. Otherwise we end up not following the specs and not returning -EPIPE several times in a row when trying to transfer data to a halted endpoint.

Revert "xhci: clear root port wake on bits if controller isn't wake-up capable"

2014-11-22T15:33:15Z

commit ff8cbf250b44 ("xhci: clear root port wake on bits if controller isn't") can cause device detection error if runtime PM is enabled, and S3 wake is disabled. Revert it. https://bugzilla.kernel.org/show_bug.cgi?id=85701 This commit got into stable and should be reverted from there as well.

USB: xhci: don't start a halted endpoint before its new dequeue is set

2014-11-22T15:33:15Z

A halted endpoint ring must first be reset, then move the ring dequeue pointer past the problematic TRB. If we start the ring too early after reset, but before moving the dequeue pointer we will end up executing the same problematic TRB again. As we always issue a set transfer dequeue command after a reset endpoint command we can skip starting endpoint rings at reset endpoint command completion. Without this fix we end up trying to handle the same faulty TD for contol endpoints. causing timeout, and failing testusb ctrl_out write tests.

USB: uas: Add no-uas quirk for Hitachi usb-3 enclosures 4971:1012

2014-11-22T15:33:15Z

These disks have a broken uas implementation, the tag field of the status iu-s is not set properly, so we need to fall-back to usb-storage for these. Cc: stable@vger.kernel.org # 3.16 Signed-off-by: Hans de Goede Signed-off-by: Greg Kroah-Hartman

USB: keyspan: fix tty line-status reporting

2014-11-19T15:22:21Z

Fix handling of TTY error flags, which are not bitmasks and must specifically not be ORed together as this prevents the line discipline from recognising them. Also insert null characters when reporting overrun errors as these are not associated with the received character. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Cc: stable Signed-off-by: Johan Hovold
