Hi all,

I don't know if I'm in the right group or even forum to ask my question but let me know if I'm wrong.

I'm owner of a second hand Headrush Pedalboard where there is a famous issue about USB port that is not working. USB connected to my laptop has been working twice, but since 2 weeks, no possibility to connect, I have checked the USB wire with some others, tested on 3 different laptop with different OS running on, and different USB port. I still doesn't work.

USB port is design to upload files on the pedalboards, or to update firmware

After having unmounted the pedalboard I found a motherboard that looks like the one of MPC Live. I have connnected a wire Serial to USB and use TeraTerm.

I have errors in the output of the terminal connected during the boot sequence :
...
001: dwc2 ff540000.usb: ff540000.usb supply vusb_d not found, using dummy regulator
001: dwc2 ff540000.usb: ff540000.usb supply vusb_a not found, using dummy regulator

...
001: usb5537 1-002d: Failed to write config file
001: usb5537 1-002d: failed to switch mode: -6

...

I have seen that there is a reset button and a recovery button but I don't know if I could use them to fix something.

Also when I put the headrush in Update Firmware mode from the screen touch, in the output of the terminal I have this message

Starting fastboot...
