Softawre can’t detect device

Hi everyone,

I recently bought a 3.5″ Turmo/Turing smart screen .
The display powers on, and Windows detects it with the USB connection sound.

In Device Manager it shows up as:
USB\***** and it creates a COM port (COM4).

However, the Turmo software always says “device disconnected” and there is no option to select the COM port manually.

Has anyone experienced this before?
Is this a driver/protocol issue or is this screen incompatible with the official software?

Any help would be appreciated. Thanks!

  Hello! Thank you very much for your reply. I actually managed to find the solution just before I received your message, and it turned out to be exactly what you described — the COM port was being used by another device/software. Even so, I really appreciate your support, because your answer would have helped me the same way. Thanks again!

  Hello! This issue is likely due to COM4 being occupied by another application. Please close any software that detects this type of USB device, then unplug and re-plug the USB screen—this should resolve the problem.
