bnusbick Posted January 24, 2016 Report Share Posted January 24, 2016 When I try to load a sketch as avr on lubuntu 14.04, it doesn't see ttyACM0. When I look at dmesg after plugging in the USB cable, I see the following: [ 3926.056332] usb 7-1: new full-speed USB device number 8 using uhci_hcd[ 3926.229344] usb 7-1: New USB device found, idVendor=1d50, idProduct=60a5[ 3926.229356] usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0[ 3926.229364] usb 7-1: Product: USB IO Board [ 3926.229370] usb 7-1: Manufacturer: Unknown [ 3926.231265] cdc_acm 7-1:1.0: This device cannot do calls on its own.

What do I need to do to be able to get the AVR usb to work under lubuntu 14.04? Thanks,Blake Quote Link to comment Share on other sites More sharing options...
