Use a libusb userspace driver after detaching kernel driver. 3. Userspace Driver (libusb) – Core Protocol Here’s a minimal C + libusb driver skeleton to detect and talk to BROM. mtk brom mode driver

If you need a (not recommended), you’d write a KMDF USB driver that handles raw bulk transfers, but userspace libusb is the standard approach today.
