# On Windows 11 host usbipd bind --busid <BUSID> # Inside WSL2 sudo upgrade_tool uf firmware.img This avoids Windows driver signature issues entirely while retaining Rockusb functionality. The Rockusb driver on Windows 11 is functional but requires test-signing mode or third-party WHQL alternatives. For professional environments, the WinUSB/Zadig approach offers better compatibility with modern Windows security defaults. Direct use of rockusb.sys is only recommended for legacy device support or isolated development workstations. Document version 1.0 – Last updated 2025 Direct use of rockusb
