* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/usb-2.6:
  USB: export autosuspend delay in sysfs
  sysfs: allow attributes to be added to groups
  USB: make autosuspend delay a module parameter
  USB: minor cleanups for sysfs.c
  USB: add a blacklist for devices that can't handle some things we throw at them.
  USB: refactor usb device matching and create usb_device_match
  USB: Wacom driver updates
  gadgetfs: Fixed bug in ep_aio_read_retry.
  USB: Use USB defines in usbmouse.c and usbkbd.c
  USB: add rationale on why usb descriptor structures have to be packed
  USB: ftdi_sio: Adding VID and PID for Tellstick
  UHCI: Eliminate asynchronous skeleton Queue Headers
  UHCI: Add macros for computing DMA values
  USB: Davicom DM9601 usbnet driver
  USB: asix.c - Add JVC-PRX1 ids
  usbmon: Remove erroneous __exit
  USB: add driver for iowarrior devices.
  USB: option: add a bunch of new device ids
  USB: option: remove duplicate device id table

			[USB] The autosuspend time delay (in seconds) used

			for newly-detected USB devices (default 2).  This

			autosuspended.  Devices for which the delay is set
