Hi I currently work on an HID driver for the Nintendo Wii Remote as Bluez GSoC project. Following, the basic driver implementation with wiimote button-input and led support. The Wii Remote (further wiimote) is a small wireless device that communicates with the host via bluetooth. It uses the HID ports but does not provide any proper HID descriptor sets and doesn't really fit into the HID class so a special driver is needed to control the device. Wiimote device: http://en.wikipedia.org/wiki/Wiimote Bluetooth details and reverse-engineered protocol: https://github.com/dvdhrm/xwiimote/blob/master/doc/PROTOCOL Protocol details (reverse engineered): http://wiibrew.org/wiki/Wiimote Since the protocol used by the wiimote is fairly complex and does not work well with HIDINPUT, I tried to copy the hidraw driver. I need to send complex initialization sequences and memory writes to the wiimote which do not fit into the "struct input_event" and thus cannot be fed to the basic output_report function. Instead I use the same function that HIDRAW uses to insert raw hid commands. However, this function is unbuffered so I added an own buffer to the driver. This patchset includes basic input-button parsing and provides the information via evdev and also provides LED support which can be set via: echo [1/0] >/sys/bus/hid/devices/<dev>/led1 or led2, led3, led4 My tree is available at (based on jikos/master): https://github.com/dvdhrm/xwiimote_kernel It gets rebased on jikos/master regularily. Userspace tools/documentation are available at: https://github.com/dvdhrm/xwiimote This is still a work in progress. Any comments are appreciated. My tree already includes further peripheral support for the wiimote like IR-cam and accelerometer, however, these peripherals get fairly complex in initialization sequences and other stuff, so I excluded them from this first patchset. Any comments are appreciated.
