The USB LED driver exposes a undocumented sysfs interface and doesn't
use the standard kernel LED subsystem. It supports three devices:
Delcom Visual Signal Indicator
The driver supports generation 1 of the device only which was
manufactured until 2008. Remove support for this device completely.
Riso Kagaku RGB LED + Dream Cheeky Webmail Notifier
These devices are HID compliant and are supported by a new USB LED
driver under drivers/hid utilizing the kernel LED subsystem.
So let's remove the old USB LED driver.

USB Type-C Connector System Software Interface (UCSI) is
specification that defines the registers and data structures
that can be used to control USB Type-C ports on a system.
UCSI is used on several Intel Broxton SoC based platforms.
Things that UCSI can be used to control include at least USB
Data Role swapping, Power Role swapping and controlling of
Alternate Modes on top of providing general details about
the port and the partners that are attached to it.
The initial purpose of the UCSI driver is to make sure USB
is in host mode on desktop and server systems that are USB
dual role capable, and provide UCSI interface.
The goal is to integrate the driver later to an USB Type-C
framework for Linux kernel, and at the same time add support
for more extensive USB Type-C port control that UCSI offers,
for example data role swapping, power role swapping,
Alternate Mode control etc.
The UCSI specification is public can be obtained from here:

timeval is deprecated and not y2038 safe. Its size also changes according
to 32 bit/ 64 bit compilation. Replace it with 32 and 64 bit versions of
its individual fields, giving two ioctls with different code values.
The two ioctls are necessary to maintain the 32 bit and 64 bit userspace
compatibility with a 64/32 bit kernel.
Change unsigned to __u32 types for a definitive userspace interface.
This is in accordance with the psABI that the unsigned type is always
32 bits.
Also use motonic timer instead of real time to ensure positive delta
values.
Refactor usbtest_ioctl for readability to isolate the handling of the
testing timing measurement.
The official testusb userspace tool can be changed in a separate patch
to reflect the __u32 changes as well. It can use the usbtest_param_32
struct, since 32 bit seconds is long enough for test durations.

The bulk queue tests are used to show 'best performance' for bulk
transfer, we are often asked this question by users. The implementation
is the same with iso test, that is queue request at interrupt completion,
so we reuse the iso structures, and rename them as common one.
It's result should be very close to IC simulation, in order
to get that, the device side should also need to prepare enough
queue.
We have got the 'best performance' (IN: 41MB, OUT: 39MB) at i.mx platform
(USB2, ARM Cortex A9, stream mode need to enable) with below command:

Two simple test cases for interrupt endpoints are added to the usbtest.c file.
These are simple non-queued interrupt IN and interrupt OUT transfers. Currently,
only gadget zero is capable of executing the interrupt EP test cases. However,
extending the same to other gadgets is extremely simple and can be done
on-demand.
The two new tests added are
- Test 25: To verify Interrupt OUT transfer
- Test 26: To verify Interrupt IN transfer
Since the default value of wMaxPacketSize is set as 1024, so interrupt
IN transfers must be specified with the size parameter = multiple of
1024. Otherwise the default value (512) in the usbtest application fails
the transfer. See [RUN 4] for sample logs
The application logs (usbtest) and corresponding kernel logs are as
following:
[Run 1]
./testusb -a -c 10 -s 2048 -t 26 -v 511

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

TEST 11 unlinks the URB read request for N times. When host and gadget
both initialize pattern 1 (mod 63) data series to do IN transfer, the

Here's four patches to be queued to usb-next for 3.14.
One adds a module parameter to the xHCI driver to allow users to enable
xHCI quirks without recompiling their kernel, which you've already said
is fine. The second patch is a bug fix for new usbtest code that's only
in usb-next. The third patch is simple cleanup.
The last patch is a non-urgent bug fix for xHCI platform devices. The
bug has been in the code since 3.9. You've been asking me to hold off
on non-urgent bug fixes after -rc4/-rc5, so it can go into usb-next, and
be backported to stable once 3.14 is out.
These have all been tested over the past week. I did run across one
oops, but it turned out to be a bug in 3.12, and therefore not related
to any of these patches.
Please queue these for usb-next and 3.14.
Thanks,

is fine. The second patch is a bug fix for new usbtest code that's only
in usb-next. The third patch is simple cleanup.
The last patch is a non-urgent bug fix for xHCI platform devices. The
bug has been in the code since 3.9. You've been asking me to hold off
on non-urgent bug fixes after -rc4/-rc5, so it can go into usb-next, and
be backported to stable once 3.14 is out.
These have all been tested over the past week. I did run across one
oops, but it turned out to be a bug in 3.12, and therefore not related
to any of these patches.
Please queue these for usb-next and 3.14.
Thanks,
Sarah Sharp
Mark function my_memlen() as static in misc/usbsevseg.c because it is
not used outside this file.
This eliminates the following warning in misc/usbsevseg.c:
drivers/usb/misc/usbsevseg.c:60:15: warning: no previous prototype for ‘my_memlen’ [-Wmissing-prototypes]

In test_halt() we set an endpoint halt condition and return on halt verification
failure, then the enpoint will remain halted and all further tests related
to that enpoint will fail. This is because we don't tackle endpoint halt error condition
in any of the tests. To avoid that situation, make sure to clear the
halt condition before exiting test_halt().

Commit c952a8ba71 "usb: usbtest: add a
test case to support bos for queue control" will cause USB 2.01 and USB
2.10 devices with a BOS descriptor to fail case 15 of the control test.
The Link PM errata (released in 2007, updated in 2011) says:
"The value of the bcdUSB field in the standard USB 2.0 Device Descriptor
is used to indicate that the device supports the request to read the BOS
Descriptor (i.e. GetDescriptor(BOS)). Devices that support the BOS
descriptor must have a bcdUSB value of 0201H or larger."
The current code says that non-SuperSpeed devices *must* return -EPIPE,
as this comment shows:
/* sign of this variable means:
* -: tested code must return this (negative) error code
* +: tested code may return this (negative too) error code
*/
int expected = 0;
This means the test will fail with USB 2.01 and USB 2.10 devices that
provide a BOS descriptor. Change it to only require a stall response if
the USB device bcdUSB is less than 2.01.

The commit "usb: usbtest: support bos descriptor test for usb 3.0"
introduced a test for bos descriptor. And USB 2.1 device also can be
checked. So this patch extends the test coverage to support USB 2.1 device.

USB 2.1 Link PM adds to use bits[1:15] according to USB 2.0 ECN Errata for
Link Power Management spec.
Bit Encoding
0 Reserved
1 LPM
2 BESL & Altemate HIRD definitions supported
3 Recommended Baseline BESL valid
4 Recommended Deep BESL valid
11:8 Recommended Baseline BESL value
15:12 Recommended Deep BESL value
31:16 Reserved
So fix the bit mask from 0x1e to 0xfffe.

thereby tests control message queuing, protocol stalls, short reads, and
fault handling. And this patch add a test case to support queue BOS control
