ed6d949afd - Make struct usb_xfer opaque so that drivers can not access the internals
- Reduce the number of headers needed for a usb driver, the common case is just   usb.h and usbdi.h

3975e3a1ea Move usb to a graveyard location under sys/legacy/dev, it is intended that the
new USB2 stack will fully replace this for 8.0.

Remove kernel modules, a subsequent commit will update conf/files. Unhook
usbdevs from the build.

d64492c407 protect against multiple inclusion (this is useful when you
start working with third party usb modules, where sometimes it
is not easy to set the inclusion order so that there are no multiple
inclusions, yet you want to compile with high WARNS levels).

I am not sure if there is a standard for having a leading and/or trailing _
in the macro name, the usb code seems to use both.

There are still several unprotected headers here so it might be useful
to do the same thing on other files as well as the need arises.

o usb_subr.c, add delta 1.119:

  Move usb_get_string() and make it public.

o usbdi.c, bring on par with 1.106, this includes:

  - Make an iterator abstraction for looping through all descriptors.

  - Whine about not being able to figure out default language if we are debugging.

  - Move usb_get_string() and make it public.

o usbdi.h, bring on par with 1.64, this includes:

  - Make an iterator abstraction for looping through all descriptors.

  - Move usb_get_string() and make it public.

o usbdi_util.c, bring on par with 1.42, this includes:

  - Add usbd_get_protocol().

  - Use NULL instead of 0.

  - Fix (mostly harmless) typo.

  - Move utility routine from uirda.c to usbdi_util.c.

o usbdi_util.h, bring on par with 1.31, this includes:

  - Add usbd_get_protocol().

  - Move utility routine from uirda.c to usbdi_util.c.

uhid.c (1.61), author: jdolecek
   add support for USB_GET_DEVICEINFO and USB_GET_STRING_DESC ioctls,
   with same meaning as for ugen(4)

usbdi_util.h (1.29), usb_quirks.c (1.50), uhid.c (1.62),
ugen.c (1.68), usb_subr.c (1.114) author: mycroft
   Yes, some devices return incorrect lengths in their string
   descriptors.  Rather than losing, do what Windows does: just
   request the maximum size, and allow a shorter response.  Obsoletes
   the need for UQ_NO_STRINGS, and therefore these "quirks" are removed.

usb_subr.c (1.116), author: mycroft
    In the "seemed like a good idea until I found the fatal flaw"
    department...  Attempting to read a maximum-size string descriptor
    causes my kue device to go completely apeshit.  So, go back to the
    original method, but allow the device to return a shorter string than
    it claimed.

c97325b0c8 WARNING: white space diff
This code reduces the number of trailing white space to be more in line
w/ NetBSD.  I don't regenerate usbdevs, saving that for when it really
changes.

3241be7550 Synchronisation with NetBSD as of 1999/11/16:
Cleaning up the code:
- Declare many functions static
- Change variable names to make them more self explanatory
- Change usbd_request_handle -> usbd_xfer_handle
- Syntactical changes
- Remove some unused code
- Other KNF changes

Interrupt context handling
- Change delay to usbd_delay_ms were possible (takes polling mode into
  account)
- Change detection mechanism for interrupt context

Add support for pre-allocation DMA-able memory by device driver

Add preliminary support for isochronous to the UHCI driver (not for OHCI
yet).

usb.c, uhci.c, ohci.c
- Initial attempt at detachable USB host controllers
- Handle the use_polling flag with a lttle more care and only set it if
we are cold booting.

usb.c, uhci.c ohci.c, usbdi.c usbdi_util.c usb_subr.c
- Make sure an aborted pipe is marked as not running.
- Start queued request in the right order.
- Insert some more DIAGNOSTIC sanity checks.
- Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.

usb.c, usb_subr.c
- Add an event mechanism so that a userland process can watch devices
  come and go.

ohci.c
- Handle the case when a USB transfer is so long that it crosses two
  page (4K) boundaries.  OHCI cannot do that with a single TD so we make
  a chain.

ulpt.c
- Use a bigger buffer when transferring data.
- Pre-allocate the DMA buffer.  This makes the driver slightly more
  efficient.
- Comment out the GET_DEVICE_ID code, because for some unknown reason it
  causes printing to fail sometimes.

usb.h
- Add a macro to extract the isoc type.
- Add a macro to check whether the routine has been entered after splusb
  and if not, complain.

usbdi.c
- Fix a glitch in dequeueing and aborting requests on interrupt pipes.
- Add a flag in the request to determine if the data copying is done by
  the driver or the usbdi layer.

8c895d718b Major synchronisation with the NetBSD USB stack:
- Some cleanup and improvements in the uhci and ohci drivers
- Support for plugging and unplugging devices improved
- Now available is bulk transport over OHCI controllers
- Resume and suspend have been temporarily been disabled again.  Proper
  support for it is available in the uhci.c and ohci.c files but I have
  not yet spent the brain cycles to use it.
- OpenBSD now uses the USB stack as well
- Add FreeBSD tags
