Was doing some printing, and had to update the firmware to test more,
all upgrade went fine thru the Arduino IDE, so no problems there.
Removed the jumper and now it just doesnt show up anymore as serial port.
As soon as you plug in the USB the led next to the ATMega256 goes off.
If you dont power the board and only insert the usb the LD5 and LD6 light up, and stay lit, but no serial port at all.
It has worked until yesterday, and now it just suddenly stopped working.
Drivers are up2date, try’d MacOS, and Linux, both do not see the port at all, which they did before.
Any idea’s ?
