SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6001", MODE="0666", ENV{MTP_NO_PROBE}="1"

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6002", MODE="0666", ENV{MTP_NO_PROBE}="1"

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6003", MODE="0666", ENV{MTP_NO_PROBE}="1"

# USB-Blaster II

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6010", MODE="0666", ENV{MTP_NO_PROBE}="1"

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6810", MODE="0666", ENV{MTP_NO_PROBE}="1"
