hey guys,
i am realtively new to the usage of arduino.
i have an arduino MEGA (atmega2560) and i tried to test an RFID shield.
for this reason i had to change the baud rate of the serial monitor.
after this i could no longer upload any sketch.
i am using linux (fedora 15) at 32bit and 64bit. so it was no matter of the computer i tried to flash the sketch.
the compiler/avr dude says:
processing.app.SerialNotFoundException: Serial port '/dev/ttyACM2' not found. Did you select the right one from the Tools > Serial Port menu?

i had some problems with finding the USB-port but after unpluging the arduino and restarting the arduino IDE it worked, until now.
i have already read something about an equivalent problem but it did not help
at all. so i am asking you for help.
thanks for your help!
