I have my Arduino IDE 2:1.0 installed in Mint LINUX 18.2. In the tools menu, it shows my Arduino Uno r3 connected to /dev/ttyACM0. When I run dmesg, it also shows there is an Arduino board connected and shows it connected to /dev/ttyACM0. When I attempt to upload the "Blink" code to test everything out, I get the following error:
System wide configuration file is "/usr/share/arduino/hardware/tools/avrdude.conf" User configuration file is "/home/karl/.avrduderc" User configuration file does not exist or is not a regular file, skipping Using Port : usb Using Programmer : stk500v2 avrdude: usbdev_open(): did not find any USB device "usb" (0x03eb:0x2104) avrdude done. Thank you.
I have found no info on how to set this up. I have read the troubleshooting info on Arduino Playground, to no avail. Please help. Thank you in advance for your help.
