This patch fixes the long standing schedule with interrupts off problem
of the uss720 driver. The problem is caused by the parport layer calling
the save and restore methods within a write_lock_irqsave guarded region.
The fix is to issue the control transaction requests required by save

Fair points, thanks.
When connected over USB2, this device reports a nonsense
bInterfaceProtocol value 6 and doesn't work with usb-storage. When
connected over USB1, the device reports the correct bInterfaceProtocol

This is patch as550 from Alan Stern.
Apparently someone changed the SCSI core so that it no longer holds the
host lock when doing a device or bus reset. usb-storage was updated at
the time, but the change was done carelessly. Some of the code depends
on that lock being held.
This patch reintroduces the host lock where needed and tries to clarify
the comments explaining why the lock is necessary. It also moves the
code that clears the TIMED_OUT and ABORTING bitflags so that it executes
as soon as the timed-out command has completed (and while the host lock
is held).

There is no need for the PXA27x OHCI to set usb power during init, since

Some OHCI implementations have differences in the way the NDP register

One change may improve some S1 or S3 resume cases, and the other
seems mostly to explain some strange state "lsusb" would show.
Two fixes:
- On resume, don't think about resuming any unpowered port, or
resetting any port with OWNER set to the OHCI/UHCI companion.
This will make some S1 and S3 resume scenarios work better.
- PORT_CSC was not being cleared correctly in ehci_hub_status_data.
This was visible at least through current versions of "lsusb",
and might have caused some other hub related strangeness.
The fix addresses all three write-to-clear bits, using the same
approach that UHCI happens to use: a mask of bits that are
cleared in most writes to that port status register.
Original patch seems to have been from from William.Morrow@amd.com
and this version (from David) finishes the write-to-clear changes.

This is a driver for the USB touchpad which can be found on post-February 2005
Apple PowerBooks.
This driver is derived from Johannes Berg's appletrackpad driver [1],
but it has been improved in some areas:
* appletouch is a full kernel driver, no userspace program is necessary
* appletouch can be interfaced with the synaptics X11 driver[2], in order
to have touchpad acceleration, scrolling, two/three finger tap, etc.
This driver has been tested by the readers of the 'debian-powerpc' mailing
list for a few weeks now and I believe it is now ready for inclusion into the
mainline kernel.
Credits go to Johannes Berg for reverse-engineering the touchpad protocol,
Frank Arnold for further improvements, and Alex Harper for some additional
information about the inner workings of the touchpad sensors.

here is a new and extended version of the sisusbvga (previously: sisusb)
driver. The patch is against 2.6.13 and updates the driver to version 0.0.8.
Additions include complete VGA/EGA text console support and a build-in
display mode infrastructure for userland applications that don't know
about the graphics internals.
Fixes include some BE/LE issues and a get/put_dev bug in the previous
version.
Other changes include a change of the module name from "sisusb" to
"sisusbvga". The previous one was too generic IMHO.
Please note that the patch also affects the Makefile in
drivers/video/console as the driver requires the VGA 8x16 font in case
the text console part is selected.
Heavily tested, as usual. Please apply.
One thing though: I already prepared for removal of the "mode" field and
the changed "name" field in the usb_class_driver structure. This will
perhaps need some refinement depending on whether you/Linus merge the
respective core changes before or after 2.6.14.

to handle the different maximum transfer sizes for rx and tx sides.
- Also from Jamie, some bugfixes:
* MDIO byteorder (to address some PPC media negotiation problems);
* Force alignment at key spots when using ax88772 framing (on some
embedded hardware, the network stack will break otherwise);
* Address some link reset problems.
It also makes this driver use the standard (5 seconds vs half second)

This starts to prepare the core of "usbnet" to know less about various
framing protocols that map Ethernet packets onto USB, so "minidrivers"
can be modules that just plug into the core.
- Remove some framing-specific code that cluttered the core:
* net->hard_header_len records how much space to preallocate;
now drivers that add their own framing (Net1080, GeneLink,
Zaurus, and RNDIS) will have smoother TX paths. Even for
the drivers (Zaurus, Net1080) that need trailers.
* defines new dev->hard_mtu, using this "hardware" limit to
check changes to the link's settable "software" mtu.
* now net->hard_header_len and dev->hard_mtu are set up in the
driver bind() routines, if needed.
- Transaction ID is no longer specific to the Net1080 framing;
RNDIS needs one too.
- Creates a new "usbnet.h" header with declarations that are shared
between the core and what will be separate modules.
- Plus a couple other minor tweaks, like recognizing -ESHUTDOWN
means the keventd work should just shut itself down asap.
The core code is only about 1/3 of this large file. Splitting out the
minidrivers into separate modules (e.g. ones for ASIX adapters,
Zaurii and similar, CDC Ethernet, etc), in later patches, will
improve maintainability and shrink typical runtime footprints.
