No power or Comm via USB

Hi,

 

After a motor wizard on my Trampa VESC Six+ via Vesc tool the USB stopped working and the controller no longer powers up via USB.

However when connecting a ST link or battery I get a blue Led and a red led that flashes once every 6 seconds.

Tried to flash via ST link but without any fix for the USB connectivety.

is there a usb chip that might need replacement?

As far as I remember trampa controllers are not wired to be powered with the USB only. My MK3 at least is not. It's not a bug but a feature. You need to connect the usb but then power the controller itself to get the USB working.
