Nayax issues with Qibixx MDB

Has anyone experienced intermittent USB disconnects with a Nayax VPOS Touch setup?

I'm troubleshooting a photo booth that uses a Nayax VPOS Touch for payments and a Qibixx MDB-USB interface for MDB communication.

The system works normally for a while, but then communication drops unexpectedly. In Windows Event Viewer I repeatedly see:

"Device USB\VID_16D0&PID_0BD7\0 has been surprise removed as it is reported as missing on the bus."

A few moments later, Windows reloads the usbser driver for the same device, which makes it look like the MDB-USB interface is disappearing and reconnecting.

What I've observed:

  • Multiple "surprise removed" events before the connection is completely lost.
  • The issue occurs with different USB cables.
  • MDB Utility eventually loses communication.
  • The device appears to disconnect and reconnect at the Windows level.

I'm trying to determine whether this is:

  • A Nayax VPOS Touch issue
  • An MDB power/voltage issue
  • A Qibixx MDB-USB issue
  • A known compatibility problem between these devices

Has anyone seen similar behavior or found a reliable fix?

Any suggestions or troubleshooting ideas would be greatly appreciated.
