Non-responsive KB2040

Post by rdkn »

I can't get my KB2040 to be recognized by my computer, (USB error 43 - Windows 11).
I was using the mcu normally whenI tried connecting it back to my computer and I can no longer use it, nor the Boot and Reset buttons respond.
I deleted the device from my computer, restarted and tried again but no success.
I was thinking this might be a bootloop case, but the buttons are not doing anything.

What voltages do you see on the RAW and 3V pins?
