This is a hardware random number generator. The driver provides both a
/dev/chaoskeyX entry and hooks the entropy source up to the kernel
hwrng interface. More information about the device can be found at

The USB ID for ChaosKey was allocated from the OpenMoko USB vendor
space and is visible as 'USBtrng' here:

OTG3 and EH Compliance Plan 1.0 talks about Super Speed OTG Verification
system (SS-OVS) which consists of an excersizer and analyzer.
USB Compliance Suite from Lecroy or Ellisys can act as such SS-OVS for
Link Layer Validation (LVS).
Some modifications are needed for an embedded Linux USB host to pass all
these tests. Most of these tests require just Link to be in U0. They do
not work with default Linux USB stack since, default stack does port
reset and then starts sending setup packet, which is not expected by
Link Layer Validation (LVS) device of Lecroy Compliance Suit. Then,
There are many Link Layer Tests which need host to generate specific
traffic.
This patch supports specific traffic generation cases. As of now all the
host Lecroy Link Layer-USBIF tests (except TD7.26) passes
with this patch for single run using Lecroy USB Compliance Suite
Version 1.98 Build 239 and Lecroy USB Protocol Analyzer version 4.80
Build 1603. Therefore patch seems to be a good candidate for inclusion.
Further modification can be done on top of it.
lvstest driver will not bind to any device by default. It can bind
manually to a super speed USB host controller root hub. Therefore, regular
hub driver must be unbound before this driver is bound. For example, if
2-0:1.0 is the xhci root hub, then execute following to unbind hub driver.
echo 2-0:1.0 > /sys/bus/usb/drivers/hub/unbind
Then write Linux Foundation's vendor ID which is used by root hubs and
SS root hub's device ID into new_id file. Writing IDs into new_id file
will also bind the lvs driver with any available SS root hub interfaces.
echo "1D6B 3" > /sys/bus/usb/drivers/lvs/new_id
Now connect LVS device with root hub port.
Test case specific traffic can be generated as follows whenever needed:
1. To issue "Get Device descriptor" command for TD.7.06:
echo > /sys/bus/usb/devices/2-0\:1.0/get_dev_desc
2. To set U1 timeout to 127 for TD.7.18
echo 127 > /sys/bus/usb/devices/2-0\:1.0/u1_timeout
3. To set U2 timeout to 0 for TD.7.18
echo 0 > /sys/bus/usb/devices/2-0\:1.0/u2_timeout
4. To issue "Hot Reset" for TD.7.29
echo > /sys/bus/usb/devices/2-0\:1.0/hot_reset
5. To issue "U3 Entry" for TD.7.35
echo > /sys/bus/usb/devices/2-0\:1.0/u3_entry
6. To issue "U3 Exit" for TD.7.36
echo > /sys/bus/usb/devices/2-0\:1.0/u3_exit

An Embedded Host High-Speed Electrical Test (EHSET) test fixture is
used to initiate test modes on a host controller in order to perform
the high speed electrical testing procedure for USB-IF compliance.
When this test fixture is connected to a host, it can enumerate as
one of several selectable VID/PID pairs, each corresponding to one
of the following test modes:
* TEST_SE0_NAK
* TEST_J
* TEST_K
* TEST_PACKET
* HS_HOST_PORT_SUSPEND_RESUME
* SINGLE_STEP_GET_DEV_DESC
* SINGLE_STEP_SET_FEATURE

This patch removes the auerswald USB driver from the linux kernel
2.6.26.
This driver was included into the kernel mainly to connect to the ISDN
framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile
and moving ISDN support, this connection was never realized, and the
only use of this driver was for device configuration. In the age of DSL,
the demand of ISDN support is getting very low.
Meanwhile, with the advent of libusb, an userspace driver was done for
the device configuration which works fine for linux and mac. (Thanks to
the libusb developers!). The userspace driver is downloadable from the
auerswald web site.
So this driver is obsolete now and has to be removed. Many thanks to all
developers which helped me to bring this driver up and working.

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.

A simple driver to turn on the charging capability of a USB BlackBerry
device when it is plugged into the machine. It does not bind to the
device, so all userspace programs can still sync properly with it.
Note, if CONFIG_USB_SUSPEND is enabled, it can play havoc with this
device as the power to the port will be shut down. This device id will
have to be added to the global blacklist table when it is created.

This "ftdi-elan" module is one half of the "driver" for
ELAN's Uxxx series adapters which are USB to PCMCIA CardBus
adapters. Currently only the U132 adapter is available and
it's module is called "u132-hcd".
When the USB hot plug subsystem detects a Uxxx series adapter
it should load this module.
Upon a successful device probe() the jtag device file interface
is created and the status workqueue started up.
The jtag device file interface exists for the purpose of
updating the firmware in the Uxxx series adapter, but as
yet it had never been used.
The status workqueue initializes the Uxxx and then sits there
polling the Uxxx until a supported PCMCIA CardBus device is
detected it will start the command and respond workqueues
and then load the module that handles the device. This will
initially be only the u132-hcd module. The status workqueue
then just polls the Uxxx looking for card ejects.
The command and respond workqueues implement a command
sequencer for communicating with the firmware on the other
side of the FTDI chip in the Uxxx. This "ftdi-elan" module
exports some functions to interface with the sequencer.
Note that this module is a USB client driver.
Note that the "u132-hcd" module is a (cut-down OHCI)
host controller.
Thus we have a topology with the parent of a host controller
being a USB client! This really stresses the USB subsystem
semaphore/mutex handling in the module removal.

The following driver provides complete interrupt-in and interrupt-out
reports (raw data) to a user program. Until now it uses the
HIDIOCGDEVINFO ioctl call, because I don't know better :-(. Perhaps, it
will be ok for you - and I will be happy, if you assign 8 minor numbers.
I have tested it in several environments and it works very well for me.
However, it has a problem with two or more devices at the same hub, if
the two or more devices need 1 ms interrupt-in transfers. Unfortunately
more than one interrupt-in transfer every ms isn't possible (ehci
driver?). This is why the min_interrupt_in_interval and
min_interrupt_out_interval are increased to 2 ms (see the corresponding
module parameters). This way, I can use two devices simultaneously at
the same hub.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
