Greetings Mr_Valentin,

Thank you for using Apple Support Communities. It seems like your MacBook Pro is having a kernel panic from the USB port. Start by resetting the SMC on the computer which controls how things power up on the computer:

How to reset the System Management Controller (SMC) on your Mac

If it persists this sounds like it is having a hardware problem. I would recommend you read this article and use it to help troubleshoot the issue.

Take care.
