Thumbs up:
drivers/hid/hid-input.c: HID Event: 0xffff 0x0
drivers/hid/hid-input.c: HID Event: 0xffff 0x42
drivers/hid/hid-input.c: HID Event: 0xffff 0x42
drivers/hid/hid-input.c: HID Event: 0xffff 0x0
drivers/hid/hid-input.c: HID Event: 0xc 0x20
Thumbs down:
drivers/hid/hid-input.c: HID Event: 0xffff 0x0
drivers/hid/hid-input.c: HID Event: 0xffff 0x41
drivers/hid/hid-input.c: HID Event: 0xffff 0x41
drivers/hid/hid-input.c: HID Event: 0xffff 0x0
drivers/hid/hid-input.c: HID Event: 0xc 0x20
TiVo:
drivers/hid/hid-input.c: HID Event: 0xffff 0x0
drivers/hid/hid-input.c: HID Event: 0xffff 0x3d
drivers/hid/hid-input.c: HID Event: 0xffff 0x3d
drivers/hid/hid-input.c: HID Event: 0xffff 0x0
drivers/hid/hid-input.c: HID Event: 0xc 0x20
Live TV:
drivers/hid/hid-input.c: HID Event: 0xffff 0x0
drivers/hid/hid-input.c: HID Event: 0xffff 0x3e
drivers/hid/hid-input.c: HID Event: 0xffff 0x3e
drivers/hid/hid-input.c: HID Event: 0xffff 0x0
drivers/hid/hid-input.c: HID Event: 0xc 0x20
So all four end with a consumer usage page event with usage id of 0x20
== "+10", aka "OSC – Increments channel by 10." The values are
consistent, but I'm not quite sure yet what the right way to implement
proper decoding is. Bed time though, will poke more later this week.
