hi,

i get an irritating issue with my arduino uno, connected via usb.

whenever i run a sketch that uses the serial monitor to view the outcome, i can program the arduino once, but then i get COM6 not found error the next time i try.

changing usb ports doesn't free it up, and the only way i can find to solve it it to reboot the machine.

the full error
Code: [Select]
processing.app.SerialNotFoundException: Serial port 'COM6' not found. Did you select the right one from the Tools > Serial Port menu?

Can you test this and say me if problem continues? http://arduino.cc/forum/index.php/topic,118440.0.html

I have replaced the winavr version, I was suspecting that was the error with serial ports

I have same issue. ERW 1.0.3 does not solve the problem still get error after 1 upload. Does anyone know how to fix this.
ERW 1.0.3 does not even give the auto fix option that says it's supposed to have.  :~

Change the COM port in device manager via system via control panel

I was having the same issue and I fixed it by moving the usb to a different port
