There is no appropriate API yet in the Linux kernel to expose these. The controller also provides a classic rumble feature for backwards compatibility. Expose this classic rumble feature using the FF framework.

The device has the same behavior as the DualShock 4 in that by default it sends a limited input report (0x1), but after requesting calibration data, it switches to an extended input report (report 49), which adds data for touchpad, motion sensors, battery and more.

Note that GH3 PC Guitars are identical, only they use different VID and PIDs. Also note that vendor id 0x12ba is used by a variety of different rhythm controllers on the ps3.

These dongles require a "magic" USB control message [1] to be sent approximately every 10 seconds otherwise the dongle will not report events where the strumbar is hit while a fret is being held. Also, inspired by a patch sent on linux-input by Sanjay Govind [2], the accelerometer is mapped to ABS_RY for tilt. Interestingly, the Wii U and PS3 dongles share the same VID and PID.

AMD SFH uses HID over PCI bus to form the HID descriptors and talks to HID clients like the monitor-sensor/iio-proxy. MP2 which is exposed as a PCI device to the x86, uses mailboxes to talk to MP2 firmware to send/receive commands.
