Where you can specific the COM ports. But for this it would be the ttyUSB ports.
I can't just use the 'erupter:all' because I also have a BFL unit and it will not start.
You can specify individual devices as well:
bfgminer -S erupter:\\.\COM3 -o -u etc
Thanks, hopefully this'll force BFGminer to see the BFL as what ever it sees it as. And the erupters as BEEs. ....really hate that 20% HW error rate.
