Samsung USB remotes (0419:0001) report six keys via standard HID usage pages
(arrow keys, OK, Power).  Kernel 2.6.25 maps those to input events (in addition
to the hiddev report).  The remaining 43 keys are reported via proprietary HID
report page and therefore by hiddev only.

Applications using hiddev and input device might process the 6 standard keys
twice.  To avoid this, the input device will be suppressed for the Samsung
remote with a quirk entry, forcing to use the hiddev device only.

LIRC already contains the proper support.

if (hid->claimed & HID_CLAIMED_INPUT)

in which an open() to an already disconnected device will submit an URB

Microsoft's wireless desktop receiver (Model 1028) has a bug in the report
descriptor -- namely, in four seperate places it uses USAGE_MIN and _MAX when
it quite obviously doesn't intend to.

In other words, it reports that it has pretty much _everything_ in 'consumer'
and 'generic desktop'.  And then the X evdev driver believes I have a mouse
with 36 absolute axes and a huge pile of keys and buttons, when I in fact,
should have zero.  255/256 in three of the cases, and 0-1024 in another.

This patch fixes the report descriptor of this device before it enters the HID
parser.

Many vendors highspeed devices give erroneously fullspeed interval value in
endpoint descriptor for interrupt endpoints. This quirk fixes up that by
recalculating the right value for highspeed device.

At the time of hid configuration this quirk calculates which highspeed interval
value gives same interval delay as, or next smaller then, what it would be if
the original value would be interpreted as fullspeed value. In subsequent urbs
that new value is used instead.

Forming the 'hid->name' in usb_hid_config() was moved up to accommodate more
descriptive printk reporting the fixup.

In this patch the quirk is set for one such device: Afatech DVB-T 2 infrared
HID-keyboard. It reports value 16 which means 4,069s in highspeed while
obviously 16ms was intended. In this case quirk calculates new value to be 8
which gives when interpreted as highspeed value 16ms as wanted. The behavior of
the device was verified to be what expected both before and after the patch.

Samsung USB remotes (0419:0001) are rejected by kernel 2.6.23, because the
report descriptor from the remote contains a 48 bit HID report field. HID 1.11
states: Fields may span at most 4 bytes.

This patch, based on 2.6.23, fixes this by modifying the internal report
descriptor in hid-quirks.c. Additional user space support (e.g. LIRC) is
required to fetch the information from the hiddev interface.

The burden to reconstruct the data is moved into userspace (lirc through hiddev).
There is no need to set HID_QUIRK_HIDDEV quirk, as the device has also output
applications, which trigger the creation of hiddev device automatically.

The device is not discoverable, and needs to be poked to set its master, the
Bluetooth device it will try to connect to when the "Home" button is pressed
without a cable plugged in.

Using libusb means disconnecting the device from its driver to get the report
descriptor. Using hiddev, we can poke it without relinquishing control over it,
so when you plug it in, it would still work as a pad.

This could be then used by sixpair program, after it is rewritten to use
hiddev instead of libusb.
