hidraw is an interface that is going to obsolete hiddev one
day.
Many userland applications are using libusb instead of using
kernel-provided hiddev interface. This is caused by various
reasons - the HID parser in kernel doesn't handle all the
HID hardware on the planet properly, some devices might require
its own specific quirks/drivers, etc.
hiddev interface tries to do its best to parse all the received
reports properly, and presents only parsed usages into userspace.
This is however often not enough, and that's the reason why
many userland applications just don't use hiddev at all, and
rather use libusb to read raw USB events and process them on
their own.
Another drawback of hiddev is that it is USB-specific.
hidraw interface provides userspace readers with really raw HID
reports, no matter what the low-level transport layer is (USB/BT),
and gives the userland applications all the freedom to process
the HID reports in a way they wish to.

The hiddev driver currently lacks 32bit ioctl compatibility, so
if you're running with a 64bit kernel and 32bit userspace, it won't
work.
I'm pretty sure that the only thing missing is a compat_ioctl
implementation as all structs have fixed size fields.
With this change I can use revoco to configure my MX Revolution mouse.

The infrared remote receiver found in the SantaRosa MacBookPro

interface (instead of HIDINPUT) so that lirc can access it using
the 'macmini' driver.
The patch below adds the required quirk for forcing the HIDDEV

quirk which forces the HIDINPUT interface to be ignored
(HID_QUIRK_IGNORE_HIDINPUT).
Note that Apple calls this receiver 'IRController4' (info taken
from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem
to all use the 'IRController1' device (USB id 05ac:8240) which
doesn't need those quirks.

Current HID layer does not report usage codes to the input layer. This feature
was previously removed, because it caused unnecessary storm of events in cases
of positioning devices, etc.
This patch adds reporting of usage codes as EV_MSC events only for key events.
We issue the EV_MSC event only if the state of the key corresponding to the
given code has changed, so that we don't report usages that are sent in every
report even if the state hasn't changed (for example Shift/Caps Lock/...
states as sent by various keyboards).
This functionality is required at least by KeyTouch in order to provide
convenient means for remapping the usage codes.

so, the devices which contain the same usages both in input and

for LEDs. All other output usages should be properly handled by

If, in usb_hid_configure(), we fail to allocate storage for 'usbhid',
"if (!(usbhid = kzalloc(sizeof(struct usbhid_device), GFP_KERNEL)))",
then we'll jump to the 'fail:' label where we have this code:
usb_free_urb(usbhid->urbin);
usb_free_urb(usbhid->urbout);
usb_free_urb(usbhid->urbctrl);
Since we got here because we couldn't allocate storage for 'usbhid',
what we have here is a NULL pointer dereference - ouch...

This patch (as918) introduces a new USB driver method: reset_resume.
It is called when a device needs to be reset as part of a resume
procedure (whether because of a device quirk or because of the
USB-Persist facility), thereby taking over a role formerly assigned to
the post_reset method. As a consequence, post_reset no longer needs
an argument indicating whether it is being called as part of a
reset-resume. This separation of functions makes the code clearer.
In addition, the pre_reset and post_reset method return types are
changed; they now must return an error code. The return value is
unused at present, but at some later time we may unbind drivers and
re-probe if they encounter an error during reset handling.
The existing pre_reset and post_reset methods in the usbhid,
usb-storage, and hub drivers are updated to match the new
requirements. For usbhid the post_reset routine is also used for
reset_resume (duplicate method pointers); for the other drivers a new
reset_resume routine is added. The change to hub.c looks bigger than
it really is, because mark_children_for_reset_resume() gets moved down
next to the new hub_reset_resume() routine.
A minor change to usb-storage makes the usb_stor_report_bus_reset()
routine acquire the host lock instead of requiring the caller to hold
it already.

There are some devices (for example Dell Multimedia Keyboard SK-8135) that have

hid-input maps them to ABS_VOLUME. HUT pages don't restrict volume to absolute

Adding REL_VOLUME doesn't seem feasible, nothing knows how to handle it. This
patch translates relative ABS_VOLUME events into appropriate number of series
of VOLUME_UP or VOLUME_DOWN events respectively, so that userspace sees the
correct values in the end.

Lately there have been quite a lot of bug reports against broken devices
which require us to fix their report descriptor in the runtime, before it
is passed to the HID parser. Those devices have eaten quite an amount of
our quirks space, which isn't particularly necessary - the quirks are not
needed after the report descriptor is parsed, and they just consume bits.
Therefore this patch separates the quirks for report descriptor fixup, and
moves their handling into separate code. The quirks are then forgotten as
soon as the report descriptor has been parsed.
Module parameter 'rdesc_quirks' is introduced to be able to modify these
quirks in runtime in a similar way to 'quirks' parameter for ordinary HID
quirks.

Despite this fact, the only interface of this device reports itself as a
