--6lCXDTVICvIQMz0h Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hello, Last week I heard that Microsoft's new Xbox360 uses regular USB connectors for their gamepads. Because the guys at Xbox-Linux.org already wrote a driver for Linux, I decided to buy one and write a FreeBSD driver for it. The Xbox360 gamepad is like any normal HID gamepad, except that it has been slightly crippled by Microsoft: - They don't use the regular HID interface class, but the vendor specific class in combination with an interface subclass. - Their device does not contain a HID report descriptor. The first problem was easy to solve; I just changed the USB_MATCH code to accept the UICLASS_VENDOR in combination with the interface subclass and interface protocol. Limiting vendor and product ID's should be avoided because that would block third party gamepads. The second problem was a little trickier because I had no experience with writing report descriptors. After taking a look at examples and reading documents at usb.org, I hacked one together. It's quite nice the FreeBSD driver was somewhat prepared for custom report descriptors (the Wacom Graphire gets a custom report descriptor for example). The result can be found here: http://g-rave.nl/files/xbox/freebsd-xbox360-gamepad.diff There are only some small unfinished parts though: - I don't know the output format state; I cannot control the rumbles or the LEDs on the gamepad (I constantly see green leds flashing) - For some reason, I can only read data when polling the gamepad. `usbhidctl -f <device> -al` does not return any output. Useful hints would really be appreciated; I'm not a real wizard when it comes to USB ;-) Yours, --=20 Ed Schouten <ed@fxq.nl> WWW: http://g-rave.nl/ --6lCXDTVICvIQMz0h Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQFDmLosmVI4SHXwmhERAiUTAKDSWkd/VvXandrMDUo3T3Ih+iM8ewCgwQTs fSC4YHRh9SQjFBeXtAHwOJw= =lNtj -----END PGP SIGNATURE----- --6lCXDTVICvIQMz0h--
