I'm trying G2 on an arduino Due, and the ports ACM0 and ACM1 get created, however, if I picocom -b 115200 /dev/ttyACM0 ( or 1 ) there's nothing, no output, no echo. Chillipeppr also fails to do anything with these ports.
One thing that looks interesting is that the kernel (3.16) complains about:
usb 1-3: config 1 interface 1 altsetting 0 bulk endpoint 0x2 has invalid maxpacket 256
usb 1-3: config 1 interface 1 altsetting 0 bulk endpoint 0x83 has invalid maxpacket 256
usb 1-3: config 1 interface 3 altsetting 0 bulk endpoint 0x5 has invalid maxpacket 256
usb 1-3: config 1 interface 3 altsetting 0 bulk endpoint 0x86 has invalid maxpacket 256
AFAIK, maxpackets are fixed, and should be 512 on bulk packets, can this explain why I can't talk to my board?
