When I attempt to connect to Arduino the board isn't assigned to a TTY.

dmesg output is as followed.

Code: Select all

[  570.452000] usb 3-1: USB disconnect, device number 4
[  572.118000] usb 3-1: new full-speed USB device number 5 using exynos-ohci
[  572.310000] usb 3-1: New USB device found, idVendor=2341, idProduct=0042
[  572.310000] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=220

[  572.310000] usb 3-1: SerialNumber: 8563431383935121A191

Notice that i'm not getting the standard message like this..

Code: Select all

cdc_acm 2-1:1.0: ttyACM0: USB ACM device

or something of that nature. From what I see we don't have the cdc_acm module built.

Code: Select all

pi@FriendlyELEC:~$ sudo modprobe cdc_acm
modprobe: FATAL: Module cdc_acm not found in directory /lib/modules/4.4.49-s5p4418

I haven't found an updated kernel build instructions for the 4.4 kernel yet so can't build it myself. Any help would be great.
