6 | * Currently not working for all devices. To be able to use the device | ||
7 | * in linux, it is also possible to let the windows driver upload the firmware. | ||
8 | * For that, start the computer in windows and reboot. | ||
9 | * As long as the device is connected to the power supply, no firmware reload | ||
10 | * needs to be performed. | ||
