the other way is to define the com ports. you need to go back into this thread for details.
This is what I've found in a previous thread (and will change the -S parameter accordingly):
You might also try simplifying your command line to '-S COM4' instead of '-S bitforce://./COM4'; I am running cgminer 2.3.6, 2.4.1, and 2.4.2 on Win7/64 machines with ONLY Singles (no GPUs) and I've never had to specify 'bitforce:' on my command line. Also, the long-hand form of '//./COM4' is only required for COMxx ports where 'xx' is '10' or higher.
I will also give it a try with that (it seems easier to do):
NFY are not assigned a com port since they use the HID driver
You would need the USB path and/or serial number of each device. S/N can be seen from manage panel in bfgminer and use dentify to see which is which
I've seen the serial when running bfgminer. What would the parameter looks like? -S SerialNFY1 SerialNFY2 SerialNFY4 (not using #3 for the other instance)
Thank you both of you I'll check those out tonight.
Feel happy again!
