      USB: fsl_usb2_udc: fix recursive lock · 185e3dea
      Li Yang authored
      UDC needs to release lock before calling out to gadget driver, since
      it may need to reenter.  The change fixes kernel BUG observed on rt
      kernel.

      USB: usb-serial: option: Don't match Huawei driver CD images · a7f3872c
      Michael Karcher authored
      Add the interface info matching to all Huawei cards, as they all also
      contain a Mass Storage Device interface (usually containing Windows
      drivers) which should not get bound by this driver.

      USB: pl2303: another product ID · 4be2fa18
      Steve Murphy authored
      I've just got a USB GPRS/EDGE modem branded Manufacturer Micromax Model
      MMX610U (see http://www.airtel.in/level2_t3data.aspx?path=1/106/179)
      working by adding another product ID to pl2303.  Modem info reports same
      module as  Max Arnold's i.e.SIMCOM SIM600  but  with product ID 0x0612
      (cf Ox0611).

      René Rebe authored
      Like the HP53{00,70} scanner other devices of the OEM Avision require
      the USB_QUIRK_STRING_FETCH_255 to correct set a configuration with
      "recent" Linux kernels.

      USB: usb-storage: unusual_devs update for Cypress ATACB · c7257bd2
      Alan Stern authored
      This patch (as1101) updates the unusual_devs entry for the Cypress
      ATACB pass-through.  The protocol field is changed from US_PR_BULK to
      US_PR_DEVICE, since the Cypress devices already set bInterfaceProtocol
      to Bulk-only.

      USB: EHCI: fix performance regression · fa38dfcc
      Alan Stern authored
      This patch (as1099) fixes a performance regression in ehci-hcd.  The
      fundamental problem is that queue headers get removed from the
      schedule too quickly, since the code checks for a counter advancing
      rather than making an actual time-based check.  The latency involved
      in removing the queue header and then relinking it can severely
      degrade certain kinds of workloads.
      
      The patch replaces a simple counter with a timestamp derived from the
      controller's uframe value.  In addition, the delay for unlinking an
      idle queue header is increased from 5 ms to 10 ms; since some
      controllers (nVidia) have a latency of up to 1 ms for unlinking, this
      reduces the relative impact from 20% to 10%.
      
      Finally, a logical error left over from the IAA watchdog-timer
      conversion is corrected.  Now the driver will always either unlink an
      idle queue header or set up a timer to unlink it later.  The old code
      would sometimes fail to do either.
