I have determined that BAMT does not contain the proper serial support needed to create the ttyUSB* files.
Just want to note the solution to that issue here (this has been posted by somebody elsewhere too), since I searched for it a while ago and it's somewhat frustrating to find this thread without the obvious solution for the generic Linux user without automatic ttyUSB mapping:
Depending on yourLinux distro your BFL might not show as a ttyUSB* device.
If you do a
and nothing shows up then
sudo modprobe ftdi_sio vendor=0x0403 product=0x6014
sudo chmod a+rw /dev/ttyUSB*
This reqires that you have general USB device support installed.
I got the vendor/product pair from dmesg (after plugging in the Single)
dmesg | grep -i bitforce
to find the USB device number
dmesg | grep -i vendor
to find the vendor/product codes (use the one with the matching USB device number)
compile cgminer with
cgminer -S auto
and all the usual other parameters, should find your BFL Single.
