| +Apple IR receiver Driver (appleir) |
| +---------------------------------- |
| + Copyright (C) 2009 Bastien Nocera <hadess@hadess.net> |
| + |
| +The appleir driver is a kernel input driver to handle Apple's IR |
| +receivers (and associated remotes) in the kernel. |
| + |
| +The driver is an input driver which only handles "official" remotes |
| +as built and sold by Apple. |
| + |
| +Authors |
| +------- |
| + |
| +James McKenzie (original driver) |
| +Alex Karpenko (05ac:8242 support) |
| +Greg Kroah-Hartman (cleanups and original submission) |
| +Bastien Nocera (further cleanups and suspend support) |
| + |
| +Supported hardware |
| +------------------ |
| + |
| +- All Apple laptops and desktops from 2005 onwards, except: |
| + - the unibody Macbook (2009) |
| + - Mac Pro (all versions) |
| +- Apple TV (all revisions) |
| + |
| +The remote will only support the 6 buttons of the original remotes |
| +as sold by Apple. See the next section if you want to use other remotes |
| +or want to use lirc with the device instead of the kernel driver. |
| + |
| +Using lirc (native) instead of the kernel driver |
| +------------------------------------------------ |
| + |
| +First, you will need to disable the kernel driver for the receiver. |
| + |
| +This can be achieved by passing quirks to the usbhid driver. |
| +The quirk line would be: |
| +usbhid.quirks=0x05ac:0x8242:0x08 |
| + |
| +With 0x05ac being the vendor ID (Apple, you shouldn't need to change this) |
| +With 0x8242 being the product ID (check the output of lsusb for your hardware) |
| +And 0x08 being "HID_CONNECT_HIDDEV" |
| + |
| +This should force the creation of a hiddev device for the receiver, and |
| +make it usable under lirc. |
