These devices feature multiple interfaces/endpoints: a legacy BIOS/boot
interface (endpoint 0x81), as well as 2 corsair-specific keyboard interfaces
(endpoint 0x82, 0x83 IN/0x03 OUT) and an RGB LED control interface (endpoint
0x84 IN/0x04 OUT)
Because the extra 3 interfaces are not of subclass USB_INTERFACE_SUBCLASS_BOOT,
HID_QUIRK_NOGET is not automatically set on them and a 10s timeout per-endpoint
(30s per device) occurs initialising reports on boot. We configure
HID_QUIRK_NO_INIT_REPORTS for these devices.
Additionally the left-side G1-G18 macro keys on the K95RGB generate output on
the un-opened 0x82/0x83 endpoints which causes the keyboard to stop responding
waiting for this event to be collected. We enable HID_QUIRK_ALWAYS_POLL to

The usbhid driver has inconsistently duplicated code in its post-reset,
resume, and reset-resume pathways.
reset-resume doesn't check HID_STARTED before trying to
restart the I/O queues.
resume fails to clear the HID_SUSPENDED flag if HID_STARTED
isn't set.
resume calls usbhid_restart_queues() with usbhid->lock held
and the others call it without holding the lock.
The first item in particular causes a problem following a reset-resume
if the driver hasn't started up its I/O. URB submission fails because
usbhid->urbin is NULL, and this triggers an unending reset-retry loop.
This patch fixes the problem by creating a new subroutine,
hid_restart_io(), to carry out all the common activities. It also
adds some checks that were missing in the original code:
After a reset, there's no need to clear any halted endpoints.
After a resume, if a reset is pending there's no need to
restart any I/O until the reset is finished.
After a resume, if the interrupt-IN endpoint is halted there's
no need to submit the input URB until the halt has been
cleared.

The critical section protected by usbhid->lock in hid_ctrl() is too
big and because of this it causes a recursive deadlock. "Too big" means
the case statement and the call to hid_input_report() do not need to be
protected by the spinlock (no URB operations are done inside them).
The deadlock happens because in certain rare cases drivers try to grab
the lock while handling the ctrl irq which grabs the lock before them
as described above. For example newer wacom tablets like 056a:033c try
to reschedule proximity reads from wacom_intuos_schedule_prox_event()
calling hid_hw_request() -> usbhid_request() -> usbhid_submit_report()
which tries to grab the usbhid lock already held by hid_ctrl().
There are two ways to get out of this deadlock:
1. Make the drivers work "around" the ctrl critical region, in the
wacom case for ex. by delaying the scheduling of the proximity read
request itself to a workqueue.
2. Shrink the critical region so the usbhid lock protects only the
instructions which modify usbhid state, calling hid_input_report()
with the spinlock unlocked, allowing the device driver to grab the
lock first, finish and then grab the lock afterwards in hid_ctrl().
This patch implements the 2nd solution.

The PID driver (usbhid/hid-pidff.c) does not set the effect ID when
uploading an effect. The result is that the initial upload works but
subsequent uploads to modify effect parameters are all directed at the
last-created effect.
The targeted effect ID must be passed back to the device when effect
parameters are changed. This is done at the start of
"pidff_set_condition_report", "pidff_set_periodic_report" etc. based on
the value of "pidff->block_load[PID_EFFECT_
BLOCK_INDEX].value[0]".
This value is only ever set during pidff_request_effect_upload.
The result is stored in "pidff->pid_id[effect->id]" at the end of
pid_upload_effect, for later use. However, if an effect is modified and
re-sent then this identifier is not being copied back from
pidff->pid_id[effect->id] before sending the command to the device. The
fix is to do this at the start of pidff_upload_effect.

Based on a patch from: Nikolai Kondrashov <Nikolai.Kondrashov@redhat.com>
Most of the tablets handled by hid-uclogic already use MULTI_INPUT.
For the ones which are not quirked in usbhid/hidquirks, they have a
custom report descriptor which contains only one report per HID
interface. For those tablets HID_QUIRK_MULTI_INPUT is transparent.
According to https://github.com/DIGImend/tablets, the only problematic
tablet currently handled by hid-uclogic is the TWHA60 v3. This tablet
presents different report descriptors from the ones currently quirked.
This is not a problem per se, given that this tablet is not supported
currently in this version (it needs the same command as a Huion to
start forwarding events).

The FF2 driver (usbhid/hid-pidff.c) sends commands to the stick during ff_init.
However, this is called inside a block where driver_input_lock is locked, so
the results of these initial commands are discarded. This behavior is the
"killer", without this nothing else works.
ff_init issues commands using "hid_hw_request". This eventually goes to
hid_input_report, which returns -EBUSY because driver_input_lock is locked. The
change is to delay the ff_init call in hid-core.c until after this lock has
been released.
Calling hid_device_io_start() releases the lock so the device can be
configured. We also need to call hid_device_io_stop() on exit for the lock to
remain locked while ending the init of the drivers.

New Genius MousePen i608X devices have a new id 0x501a instead of the
old 0x5011 so add a new #define with "_2" appended and change required
places.
The remaining two checkpatch warnings about line length
being over 80 characters are present in the original files too and this
patch was made in the same style (no line break).
Just adding a new id and changing the required places should make the
new device work without any issues according to the bug report in the
following url.

When events occurs while no one is listening to the node (hid->open == 0
and usb_kill_urb() called) some events are still stacked somewhere in
the USB (kernel or device?) stack. When the node gets reopened, these
events are drained, and this results in spurious touch down/up, or mouse
button clicks.
The problem was spotted with touchscreens in fdo bug #81781 [1], but it
actually occurs with any mouse using hid-generic or touchscreen.
A way to reproduce it is to call:
$ xinput disable 9 ; sleep 5 ; xinput enable 9
With 9 being the device ID for the touchscreen/mouse. During the "sleep",
produce some touch events or click events. When "xinput enable" is called,
at least one click is generated.
This patch tries to fix this by draining the queue for 50 msec and
during this time frame, not forwarding these old events to the hid layer.
Hans completed the explanation:
"""
Devices like mice (basically any hid device) will have a fifo
on the device side, when we stop submitting urbs to get hid reports from
it, that fifo will fill up, and when we resume we will get whatever
is there in that fifo.

Enable the always-poll quirk for Elan Touchscreens found on some recent
Samsung laptops.
Without this quirk the device keeps disconnecting from the bus (and is
re-enumerated) unless opened (and kept open, should an input event
occur).
Note that while the device can be run-time suspended, the autosuspend
timeout must be high enough to allow the device to be polled at least
once before being suspended. Specifically, using autosuspend_delay_ms=0
will still cause the device to disconnect on input events.

Add quirk to make sure that a device is always polled for input events
even if it hasn't been opened.
This is needed for devices that disconnects from the bus unless the
interrupt endpoint has been polled at least once or when not responding
to an input event (e.g. after having shut down X).

This patch changes the way usbhid carries out Clear-Halt and reset.
Currently, after a Clear-Halt on the interrupt-IN endpoint, the driver
immediately restarts the interrupt URB, even if the Clear-Halt failed.
This doesn't work out well when the reason for the failure was that
the device was disconnected (when a low- or full-speed device is
connected through a hub to an EHCI controller, transfer errors caused
by disconnection are reported as stalls by the hub). Instead now the
driver will attempt a reset after a failed Clear-Halt.
The way resets are carried out is also changed. Now the driver will
call usb_queue_reset_device() instead of calling usb_reset_device()
directly. This avoids a deadlock that would arise when a device is
unplugged: The hid_reset() routine runs as a workqueue item, a reset
attempt after the device has been unplugged will fail, failure will
cause usbhid to be unbound, and the disconnect routine will try to do
cancel_work_sync(). The usb_queue_reset_device() implementation is
carefully written to handle scenarios like this one properly.

when connected, and a delay before its initialization. This patch adds the
quirk for this device, which causes the delay to disappear.
