Pin2dmd don't statup anymore

[Thunder1001]

hi,

I did a clean install from Windows etc...

Also did a firmware update from my Pin2dmd.

But now, if i shutdown my cab and pull and switch-off the mainpower.

After turning it back on, my dmd don't show up anymore in my device manager.

If i pull out the usb on myNucleo board and put it in the maintenance usb port, the dmd appears again in my device manager.

if i pull out the usb then from the maintenance usb port and put it back to the normal usb port, the dmd is still in my device manager and works fine.

But after when i repeat and shutdown the cab again, it's gone again.

Somebody can help?
