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