HID: Support Samsung IR remote
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.

HID: force hiddev creation for SONY PS3 controller
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

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.
