HID driver for Apple IR receivers (USB HID, vendor 0x05ac).
Supports Apple Remote and generic IR remotes using NEC protocol.
Supported hardware:
- Apple IR Receiver (0x8240, 0x8241, 0x8242, 0x8243, 0x1440)
Apple Remote protocol (proprietary 5-byte HID reports):
- Key down/repeat/battery-low detection
- 17-key mapping with two-packet command support
- Synthesized key-up via 125ms callout timer
Generic IR remotes (NEC protocol):
- Format: [0x26][0x7f][0x80][code][~code]
- Checksum: code + ~code = 0xFF
- Default keymap with 8 common codes
- See: https://techdocs.altium.com/display/FPGA/NEC+Infrared+Transmission+Protocol
Output via evdev with standard KEY_* codes.
Raw HID access available at /dev/hidraw0 for custom remapping.
Based on protocol reverse-engineering by James McKenzie et al.
Reference: drivers/hid/hid-appleir.c (Linux)
Tested on Mac Mini 2011 (0x05ac:0x8242).
