When I plug the CRYPTO-BOX into the USB port, the device is not recognized. Why does the red LED light on the dongle not light up?


Try to attach the CRYPTO-BOX to another USB port. If the problem still exists, please make sure that you have installed the latest CRYPTO-BOX device drivers with CBUSetup.

To make sure that any old drivers are removed and the latest drivers are installed, we recommend the following steps:

  • Unplug the CRYPTO-BOX from the USB port
  • Download and execute CBUSetup.exe, choose the "Uninstall" option
  • After uninstallation has finished, restart the computer
  • Execute CBUSetup.exe again and choose the "Install" option
  • Plug in the CRYPTO-BOX, it will be detected automatically

If this does not solve the problem, please send us the MARX Analyzer report of your computer.
