Hello
When ever i connect one of these devices onto my Ubuntu 13.10 box it shows up at /dev/ttyACM0 - not /dev/ttyUSB0 etc.
Anyone know why ? is this normal?
Also,
Ive tried compiling minerd from
https://github.com/gridseed/usb-miner/tree/master/software/cpuminer - and while mining - it appears to be working, but its not submitting shares - any clues on why this is?
root@ubuntu:/home/sysadmin/cpuminer# ./minerd -a scrypt -G /dev/ttyACM0 -o stratum+tcp://us.xxx.com:3334 -O alexuk.1:x -D -P -F 600 -2
