R8A66597 is similar to SH7723 USB 2.0 Host/Function module.
In addition, the USB of SH7366 is compatible with SH7723.
It can support SH7723 USB host by changing Kconfig.

* wMaxPacketSize is le16; copying it to a field of local structure and then
using that field as host-endian (size of object to be allocated) is broken.
* bMaxPacketSize0 is 8-bit; feeding it to le16_to_cpu() is bogus and since the
result is used as host-endian, it's not even misspelled cpu_to_le16().

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.

This patch (as1098) changes the way ehci-hcd schedules its periodic
Iso transfers. That the current scheduling code is wrong is clear on
the face of it: Sometimes it returns -EL2NSYNC (meaning that an URB
couldn't be scheduled because it was submitted too late), but it does
this even when the URB_ISO_ASAP flag is set (meaning the URB should be
scheduled as soon as possible).
The new code properly implements as-soon-as-possible scheduling,
assigning the next unexpired slot as the URB's starting point. It
also is more careful about checking for Iso URB completion: It doesn't
bother to check for activity during frames that are already over,
and it allows for the possibility that some of the URB's packets may
have raced the hardware when they were submitted and so never got used
(the packet status is set to -EXDEV).
This fixes problems several people have experienced with USB video
applications.

This patch (as1097) fixes a bug in the remote-wakeup handling in
ehci-hcd. The driver currently does not keep track of whether the
change-suspend feature is enabled for each port; the feature is
automatically reset the first time it is read. But recent changes to
the hub driver require that the feature be read at least twice in
order to work properly.
A bit-vector is added for storing the change-suspend feature values.

This patch (as1096) fixes an annoying problem: When a full-speed or
low-speed device is plugged into an EHCI controller, it fails to
enumerate at high speed and then is handed over to the companion
controller. But usbcore logs a misleading and unwanted error message
when the high-speed enumeration fails.
The patch adds a new HCD method, port_handed_over, which asks whether
a port has been handed over to a companion controller. If it has, the
error message is suppressed.

This patch (as1095) cleans up the HCD glue and several of the EHCI
bus-glue files. The ehci->is_tdi_rh_tt flag is redundant, since it
means the same thing as the hcd->has_tt flag, so it is removed and the
other flag used in its place.
Some of the bus-glue files didn't get the relinquish_port method added
to their hc_driver structures. Although that routine currently
doesn't do anything for controllers with an integrated TT, in the
future it might. So the patch adds it where it is missing.
Lastly, some of the bus-glue files have erroneous entries for their
hc_driver's suspend and resume methods. These method pointers are
specific to PCI and shouldn't be used otherwise.
(The patch also includes an invisible whitespace fix.)

This patch (as1094) changes the output of the "descriptors" binary
attribute. Now it will contain the device descriptor followed by all
the configuration descriptors, not just the descriptor for the current
config.
Userspace libraries want to have access to the kernel's cached
descriptor information, so they can learn about device characteristics
without having to wake up suspended devices. So far the only user of
this attribute is the new libusb-1.0 library; thus changing its
contents shouldn't cause any problems.
This should be considered for 2.6.26, if for no other reason than to
minimize the range of releases in which the attribute contains only the
current config descriptor.
Also, it doesn't hurt that the patch removes the device locking --
which was formerly needed in order to know for certain which config was
indeed current.

There is a potential deadlock when the usb_generic driver is unbound
from a device. The problem is that generic_disconnect() is called
with the device lock held, and it removes a bunch of device attributes
from sysfs. If a user task happens to be running an attribute method
at the time, the removal will block until the method returns. But at
least one of the attribute methods (the store routine for power/level)
needs to acquire the device lock!
This patch (as1093) eliminates the deadlock by moving the calls to
create and remove the sysfs attributes from the usb_generic driver
into usb_new_device() and usb_disconnect(), where they can be invoked
without holding the device lock.
Besides, the other sysfs attributes are created when the device is
registered and removed when the device is unregistered. So it seems
only fitting for the extra attributes to be created and removed at the
same time.

Uninitialised Apple iSight drivers present with a distinctive USB ID.
Once firmware has been uploaded, they disconnect and reconnect with a
new ID. At this point they can be driven by the uvcvideo driver. As this
is unique to the Apple cameras and not functionality shared by any other
UVC devices, it makes sense to provide the firmware loading
functionality in a separate driver. This driver will read an isight.fw
file extracted from the Apple driver using the tools at
http://bersace03.free.fr/ift/ and upload it to the camera. It will also
handle the case where the device loses its firmware during hibernation
and must have it reloaded.

Commit 7329e211b987a493cbcfca0e98c60eb108ab42df ("USB: root hubs don't
lie about their number of TTs") requires the various platform EHCI
glue modules to set ->has_tt if the root hub has a Transaction
Translator.
The Orion EHCI root hub does have a Transaction Translator, so set
->has_tt in ehci_orion_setup(). This fixes oopsing on plugging in a

Various fixes to Atmel's high speed UDC driver.
* Issue some missing disconnect() calls. Currently they are only made
when VBUS power goes away (on boards where the driver can sense such
changes), but that's not enough for gadget drivers to clean out all
the state that's needed. Missing calls were:
- After USB reset, before starting enumeration.
- When unregistering a gadget driver, before unbind().
* Don't assume gadget drivers provide disconnect callbacks; make sure
to not call through a null pointer!
* When the driver doesn't provide an unbind() callback, refuse to
unregister it.
Also remove two bogus "error" messages:
* Related to mis-handling of disconnect() ... don't emit error messages
for disconnect() handlers that disable endpoints. All of them should
be doing that; the problem is (unfixed) oddness in atmel_usba_udc.
* Don't emit a diagnostic for a curious and transient nonfatal error
that shows up sometimes with EP0.
Those messages spammed syslog, for no good reason.

Microchip has changed the PICDEM FS USB demo device (0x04d8:000c)
to use bulk transfer and not interrupt transfer. So I've updated the libusb
based program here (Post #31).
http://forum.microchip.com/tm.aspx?m=106426&mpage=2
So I believe that the in-kernel ldusb driver will no longer work with the

Enables the SD-Card interface on the GI 0401 HSUPA card from Option.
The unusual_devs.h entry is necessary because the device descriptor is
vendor-specific. That prevents usb-storage from binding to it as an
interface driver.

Bugfix some serial gadget descriptors:
- Stop mangling the low bits (controller type ID) of bcdDevice;
just use the high bits for a driver revision code.
- Serial numbers that aren't specific to individual devices
are useless; stop reporting "0" for this.
- Since it's not part of a CDC-conformant function, the "bulk only"
configuration shouldn't be using "CDC Data" as its interface class.
Switch over to using CLASS_VENDOR_SPEC (different value, 0xff).

Switch serial gadget away from a *very* old idiom: just remember
the endpoints we'll be using, instead of looking them up by name
each time. This is a net code and data (globals) shrink.
Also fix a small memory leak in the rmmod path, by working the
same as the disconnect code.

This removes a needless data structure from the serial gadget code;
it's a small code shrink, and a larger data shrink.
Since "struct usb_request" already has a "struct list_head" reserved
for use by gadget drivers, the serial gadget code doesn't need to
allocate wrapper structs to hold that list ... it can (and should!)
just use the list_head provided for that exact use.

Some cleanup/reorg of g_serial ... simplifying it, and disentangling
its structure so morphing it into a "function" driver (combinable with
other interfaces) should be less painful.
- Remove most forward declarations
* put tty and gadget driver structs after their contents
* snug module init/exit decls next to their functions
* reordered some functions
- Other cleanup:
* convert a funky macro to an inline function
* snug up module params next to their declarations
* add missing driver.owner
* add separator lines between major driver sections
- Add comments re potential parameter/#define changes:
* only supports one port (shrank GS_NUM_PORTS)
* changing from 9600-8-N-1 affects multiple sites
- Remove net2280-specific optimization ... it was being done
way too late, can be done by net2280 module options, and in
any case doesn't matter at any sane serial data rates.
There are no behavioral changes, but the macro thing saves I-space.

This device is not a serial port, but a virtual CD-ROM device. For
example with my Novatel MC950D:
lsusb -v -d 1410:5010 | grep InterfaceClass
bInterfaceClass 8 Mass Storage
After some time (ca. 5min) or if virtual CD is ejected, device id
changes to 1410:4400:
% lsusb -v -d 1410:4400 | grep InterfaceClass
bInterfaceClass 255 Vendor Specific Class
bInterfaceClass 255 Vendor Specific Class
Variable name says that 0x5010 is a Novatel U727, but searching in
internet shows, that this device also provides virtual CD that should be
ejected before use. Product id for serial port in this case is 0x4100.

The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:
May 3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
May 3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22
Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.
