Is there a way to have cpuminer automatically find all of the Gridseed 5-chip devices rather than specify each one via the --gc3355=/dev option?
If you're on Linux, you can use this command:

Code:
minerd -o stratum+tcp://pool.com -u USERNAME -p PASSWORD --gc3355-autotune --gc3355=`ls -m /dev/ttyACM* | sed -e 's/, /,/g' | tr -d '\n'` --freq=1200

Thanks! I'm on a Raspberry Pi, so it's Linux.

But when I do the following command on my current GridSeed rig (running cgminer; haven't moved over to minerd yet), I get an error:

Code:
sudo ls -m /dev/ttyACM*
ls: cannot access /dev/ttyACM*: No such file or directory

But in checking the siklon/cpuminer-gc3355 read me on github it appears that cgminer is somehow responsible for preventing ttyUSB or ttyACM devices from being visible. I guess I need to quit cgminer and reboot in order to work around it. I'll try that on my test rig when I get home tonight.

But wouldn't it be a nice feature to have minerd just find all of the GSDs on its own? Maybe something like this syntax: "--gc3355=ALL". Seems like a natural compliment to the auto tune feature.

Also, the competition (like cgminer) finds all the units simply enough. And I think bfgminer supports a similar "ALL" syntax (although I could be misremembering).
