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.Signed-off-by: Jiri Kosina

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.

This patch fixes the problem, that Japanese MacBook doesn't recognize some keys
like '\'(yen, or backslash), '|'(pipe), and '_'(underscore).It is due to that MacBook JIS keyboard (jp106) sends wrong report descriptor.
It saids "logical maximum = 0x65", so Keyboard.0089 is mapped to Key.Unknown,
while it should be accepted as Key.Yen.Signed-off-by: Tomoya Adachi

The infrared remote receiver found in the SantaRosa MacBookPro
laptops (MacBookPro3,1) need to be forced to expose a HIDDEV
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
interface to be activated (HID_QUIRK_HIDDEV) and introduces a new
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.Signed-off-by: Stelian Pop

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 solves that little problem by adding a new
'fail_no_usbhid:' label after the problematic calls to
usb_free_urb() and jumps to that one instead, in the problem case.Signed-off-by: Jesper Juhl

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.Signed-off-by: Alan Stern

This patch (as886) adds the controversial USB-persist facility,
allowing USB devices to persist across a power loss during system
suspend.The facility is controlled by a new Kconfig option (with appropriate
warnings about the potential dangers); when the option is off the
behavior will remain the same as it is now. But when the option is
on, people will be able to use suspend-to-disk and keep their USB
filesystems intact -- something particularly valuable for small
machines where the root filesystem is on a USB device!Signed-off-by: Alan Stern

The keyboard 0x046d/0xc311 needs reset leds quirk

This keyboard has wireless mouse which has left, middle, right buttons and
2-dimensional scrolling wheel. Unfornetuly, this wheel reports side scrolling
events and 11 or 12 button events at the same time.I've wrote a patch to fix this mapping. I'm not sure if this mapping is proper
for buttons, because , for example, there is no entry for "burn cd" in input.h.The patch also supress 11 and 12 button events from mouse when you scroll the
wheel left and right. With this patch, only side scrolling events are
reported. (This mouse has only 4 buttons and 2D wheel. There is no such
buttons like 11 and 12.)Signed-off-by: Jiri Kosina

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.Signed-off-by: Jiri Kosina

Petalynx Maxter remote control [1] 0x18b1/0x0037 emits 0xfa and 0xfc from
consumer page (reserved in HUT 1.12) for back and more keys. It also emits
a few usages from LOGIVENDOR page, which need adding.Also, this device has broken report descriptor - the reported maximum is too
low - it doesn't contain the range for 'back' and 'more' keys, so we need to
bump it up before the report descriptor is being parsed.Besides all this, it also requires NOGET quirk.
This patch does so.

Microsoft SideWinder GameVoice driver is a trivial device with a few buttons
(0x09 HID usage) and an audio connector, which just forwards the audio input
into oridinary sound card present in the computer.Despite this fact, the only interface of this device reports itself as a
Telephony/Headset type of HID device. This is apparently incorrect - the device
itself doesn't provide any audio/telephony functionality. This is achieved in
userland application which only needs to receive the button events from the HID
driver.This patch establishes a new quirk which forces hid-input to claim a device it
will otherwise leave untouched.Reported-by: Tomas Carnecky

There have been many reports recently about broken HID devices, the
diagnosis of which required users to recompile their kernels in order

possible to control debugging output produced by HID code by supplying
'debug=1' module parameter.Signed-off-by: Jiri Kosina

Certain versions of Cypress USB barcode readers (this problem is known to
happen at least with PIDs 0xde61 and 0xde64) have report descriptor which
has swapped usage min and usage max tag. This results in HID parser failing
for report descriptor of these devices, as it (wrongly) requires allocating
more usages than HID_MAX_USAGES.Solve this by walking through the report descriptor for such devices, and swap
the usage min and usage max items (and their values) to be in proper order.Reported-by: Bret Towe

It turns out that there are broken devices out there that incorrectly
report VID/PID as 0x000, see http://lkml.org/lkml/2007/4/27/496Therefore we should not confuse users by dumping warnings and stacktraces
in such situation. It is not possible to add quirks for such horribly
broken devices, but currently that's not needed.Signed-off-by: Jiri Kosina
