Requesting two PIDs under VID 1209 for TuFFrabit open source game controllers
This PR adds an org page for TuFFrabit and two PID allocations:
• 1209:70AD — Tuffpad (source (https://github.com/tuffrabit/rasp-pi-pico-narwhal)): a one-handed gamepad (20-key keypad, analog stick, 5-way d-pad) built on an off-the-shelf RP2040 board, running open source CircuitPython firmware (GPL-3.0).
• 1209:70A7 — Tuffjoystick (source (https://github.com/tuffrabit/waveshare-joystick), Seeed variant (https://github.com/tuffrabit/seeed-joystick)): a one-handed analog joystick with integrated keypad, same firmware architecture, sold on two different off-the-shelf RP2040 carrier boards.
Why two PIDs: the Tuffpad's HID report descriptor differs from the Tuffjoystick's (the Tuffpad includes an 8-way hat switch; the joystick does not), and the two product lines evolve their descriptors independently. Sharing a VID/PID across devices with differing descriptors causes stale per-device configuration
in host OS controller caches, so each product line gets its own PID.
Why the Tuffjoystick PID spans two repos: the Seeed and Waveshare board variants are the same device at the USB level — byte-identical HID report descriptors and identical behavior — so they share one PID.
All firmware and the companion management app are public and GPL-3.0 licensed with LICENSE files in each repo. The devices are sold commercially as finished hardware, with all design firmware remaining open source.
