  • * USB Relay Kernel Driver

    A Linux kernel driver and CLI for USB relay boards.

    Oct 2025 – Dec 2025 · shipped

    • Kernel module that binds to the board's FTDI FT232R chip and exposes each board as /dev/usbrelayN, with a one-byte mask ABI that drives all 8 channels.
    • Enables FTDI bit-bang mode with vendor USB control requests, so all 256 output states fit in a single byte write.
    • Handles hot-plug through probe/disconnect, endpoint discovery, and bulk transfers with 1 s timeouts.
    • Supports up to 4 boards at once, with IDA minor allocation, a mutex per device, and leak-free cleanup on every error path.
    • Includes relayctl, a user-space CLI that turns commands like "set 1 on" into bit masks, with a functional test script.
