splitting block erupters into groups

[helipotte]

Might be a dumb question but here goes.

I have about 100 erupters, want only 50 to show in a window.  All are connected to the same computer (Win 7 x64).  Using cgminer 3.6.6.

Reason for this is I use these to mine smaller SHA256 alts.  This way I can mine two coins at once.  Banks of many erupters seem to keep up with fast

coins quite well, if set up correctly.  Thought it could be done by specifying com port range in config  but winusb driver does not seem to assign com

ports to erupters.

cgminer doesn't use com ports, as the READMEs say

Read about the --usb command in the main README

So to clarify, if I wanted to mine with two 49 port block erupter groups using two cgminer windows, in the config for each one I would put:

--usb :49

This way the first instance would only detect 49 of the 98 units and the second instance would detect the rest.

Is the correct?

I would use "--usb ICA:49"

But if you only have block erupters for USB miners then you are correct.  I would set a number for the second instance too.
