Windows 10 USB reboot Rambo

I have a mini rambo with windows 10 pc.

when i connect the rambo the board continue to reboot by it self after 3 seconds it show the ready screen

it was working until yesterday without issue

i tried different cables and i have the same issue

I tried different USB port same problem

i have installed the Rambo Driver

i have a not detected device but not sure it is related with the board. When i remove it on the follow reboot it come back

i tried to boot the same pc with linuxCNC and there is no problem

i tried to connect the rambo to a Mac and there are no problem

any idea?

Fo you have repetier server installed? Maybe it is connecting, which causes a reset? Or some other program that is trying to connect to a serial port?
