I seem to have an Arduino Mega2560 that seems to have a usb issue. My pc can see it and read information off of it, but I am unable to send information to it. I use it as a 3d printer board and it can read the sensors off the printer but my pc times out when trying to send commands to it. I am also unable to send a new firmware to the board. I get avrdude: timeout for uploading. The serial Monitor does see it and reads everything out. The L led light is always illuminated.
I have tried using different USB cables, reset drivers and I even tried a different pc.
I'm pretty sure its fried but if anyone has any troubleshooting ideas I'm open.
I had that happen when the baud rate got changed by mistake. Mine is @25000. but when it stopped working, I found the software settings got set lower. Putting it back fixed my problem
The baud rate is set @ 25000 if it is different then that I just get corrupted and garbled information back. So the baud rate is correct on both computers I tried this with.
