When David added an entry to the gadget_chips.h file for the dummy_hcd
driver, he mistakenly used the name "dummy_udc" rather than "dummy_hcd".
The mistake is understandable, since other controllers use "_udc" in their
names and it is illogical to put "_hcd" in a _device_ controller's name.

This patch updates the dummy_hcd driver and changes the gadget name to
agree with the gadget_chips.h entry.

This patch changes the UHCI driver's bus-release routine; now it will
correctly finish all pending but not-yet-completed URBs.  This fixes a
reported bug, when trying to rmmod uhci-hcd while using a USB mouse under
X.  Also, the patch changes a variable name from ...hs... to ...fs...
("high speed" -> "full speed") -- something I accidentally omitted in an
earlier patch.

This patch imports the endpoint auto-config library into the file-storage
gadget, simplifying the code needed for endpoint selection and removing
almost all dependencies on the controller type from the driver.  It also
changes some log messages for reporting fatal problems from INFO to ERROR.

This patch imports the config-buffer library into the file-storage gadget,
simplifying and decreasing the amount of code needed for assembling
configuration descriptors.  It also changes the driver to remove any
pretense at bus-powered operation and to use the new DUALSPEED
configuration option.  This is in line with recent changes made to other
gadget drivers.

Well, when I did the grep that bug wasn't there; it
was just integrated on Feb 26!

The first part makes it use usb_reset_configuration() like
it did before ... I'm surprised this driver hasn't been
generating "it deadlocks during probe" reports.

The second part prints a diagnostic if the configuration
wasn't set right; the fix would use hotplug and sysfs.

  here's a small patch for omninet.c .

the attached patch should do the renaming everywhere hid or hid.o was
mentioned. It also removes all references to *.o module names.

Whoops, I missed something.  You should apply this patch too.

The RNDIS spec license agreement does NOT require tacking any
GPL-incompatible restrictions on the results of _using_ the
spec:

   "... may be used solely for the purpose of implementing
    the RNDIS protocol message set to interface with ..."
   (the two cases identified in the text)

And that's all the implementation does -- end of story.

This died a while ago, but lingers on in defconfigs.

datafab.c has an often-seen bug: the SCSI READ_CAPACITY command
does not need the number of sectors but the last sector.

I just tried the CF and SM parts of a 5-in-1 card reader.
The CF part works with US_PR_DATAFAB when the bug mentioned is fixed.
The SM part works with US_PR_SDDR55.
(Revision Number is 17.08 - that in case the 0000-ffff
should prove to be too optimistic.)

We still must discuss what setup to use for readers like this -
I have several of them - that require different drivers for
different LUNs. As it is now one has to compile usb-storage
twice, once with CONFIG_USB_STORAGE_DATAFAB defined and once
without, and remove one usb-storage.ko and insert the other
to go from CF to SM. (And that hangs with 2.6.4 so a reboot
is required..)

This patch fixes a bug in ftdi_sio.c where the driver wouldn't unlink the
read urb if the user application cleared the HUPCL flag on termios->c_cflag.

drivers/usb/gadget/epautoconf.c: In function `ep_matches':
drivers/usb/gadget/epautoconf.c:175: error: `typeof' applied to a bit-field

I've posted all these before, the only notable change is
treating that one gphoto2 case as warn-and-continue rather
than return-with-failure.


usb_set_configuration() cleanup

 * Remove it from the USB kernel driver API.  No drivers need it now,
   and the sysadmin can change bConfigurationValue using sysfs (say,
   when hotplugging an otherwise problematic device).

 * Simpler/cleaner locking:  caller must own dev->serialize.

 * Access from usbfs now uses usb_reset_configuration() sometimes,
   preventing sysfs thrash, and warns about some dangerous usage
   (which gphoto2 and other programs may be relying on).  (This is
   from Alan Stern, but I morphed an error return into a warning.)

 * Prevent a couple potential "no configuration" oopses. (Alan's?)

 * Remove one broken call from usbcore,  in the "device morphed" path
   of usb_reset_device().  This should be more polite now, hanging
   that one device rather than khubd.

This updates the existing Ethernet gadget driver to
support an additional RNDIS configuration on all
current USB controllers that can support one.

It also includes a bit more work to address the complex
autoconfiguration of this driver.  Needs testing on PXA.

Patch (mostly) contributed by Robert Schwebel, and developed
with support from Auerswald GmbH.

This patch adds the RNDIS message engine and kbuild/kconfig
support for it.  This is currently labeled EXPERIMENTAL.

Patch contributed by Robert Schwebel, and developed with
support from Auerswald GmbH.

Minor unlink tweaks, including a case where SMP could oops
if it were abused, as if from 'usbtest' or 'stir4200'.

Prevents an oops with some other patchsets.


Clear some pointers after the memory is kfreed, to avoid
making some other patch combinations oops.

These are "obvious" locking fixes:  using the right lock
to protect interface claim/release (should be the driver
model bus lock, not BKL).

This patch continues the update process for the cur_altsetting change.
The drivers in usb/input were all in good shape and needed only minimal
changes.

Mostly from Benjamin Herrenschmidt:

  - prevent usbcore from asking the HCD root hub code
    to read registers on one more suspend path (some
    hardware gets upset in those cases);

  - try handling a "device died" cleanup case better

  - add some wmb() calls in spots that could matter
    on some hardware

The 2.6 code for Intel's IXP4xx NPU line has been updated to
remove all references to IXP42x or IXP425 and replace it
with IXP4XX, including config options and file names. This
patch updates the USB-gadget pxa-udc driver with these changes.

This is a resubmission of as225, together with appropriate changes for the
g_serial driver.  David Brownell's latest g_ether update makes it
unnecessary to change that file or gadget_chips.h.



dummy_hcd is simultaneously a host controller driver and a device
controller driver.  It creates a simulated HC together with a simulated
UDC plugged into it.  Gadget drivers can run under the simulated UDC and
will appear as regular USB devices on the simulated HC.  The simulation is
reasonably (although not totally) realistic.

It's a wonderful tool for testing and developing gadget drivers without
the need for lots of additional hardware: Both the host driver and the
gadget driver can run on the same computer.  It's been available for quite
some time in David's gadget-2.6 tree and it works well.  I couldn't have
gotten the file-storage gadget running in any reasonable length of time
without it.

And the maintainer doesn't seem to want to fix it :(

Yes, it compiles.

Here's an update for the Ethernet gadget that corresponds
to the earlier one for Gadget Zero ... it gets rid of almost
all the remaining controller-specific #ifdefs in this driver.
(And also lets the driver initialize using "dummy_hcd".)

This is a significant step towards doing hardware-specific
configuration at run time (or at least init-time) rather
than compile time, but other patches will be needed to take
it the rest of the way there.   (Especially considering the
RNDIS support...)  The runtime footprint of the driver shrank
a bit, mostly because things moved into the init section.

Some hardware had the poor taste to misbehave during probe(),
which turned up a minor bug.  This fixes it:  don't try to
free a network device that hasn't been registerd.

This patch provides standard symbols for the various USB
device and endpoint feature bits, so that drivers can
use symbolic names for them.  It also changes the code
relating to endpoint halts so it uses those symbols.

Patch below fixes an obvious race in the whiteheat usb serial driver...

This allows the pegasus driver to actually be seen as a config option.
Apparently it's not that popular, though I have confirmed that it still
works on at least the netgear fv101.

you are using GFP_KERNEL in irq and __devinit with hotpluggable code.

      - use proper GFP flags
      - kill __devinit

I screwed up. This corrects it.

you are using __devinit which must not be used with USB drivers,
in addition you are using some false GFP values and fail to check
some error codes.

  - check for unlink due to removal of controller
  - correct GFP values
  - no __devinit in USB

this driver is doing DMA to the stack. Here's the obvious fix.
