For my 7 miners, I'm using:
--icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COM3 -S COM4 -S COM5 -S COM6 -S COM7 -S COM8 -S COM9
Note that I saw a post from one of the cgminer authors suggesting to use 115200:2:1 and 3.0=80. When I did that, I got errors and cgminer immediately crashed.
I'm getting about 333mh/s with the above on Win7x64.

Thanks for the tip. Yours is the best amoung so many. But I can't get any to work starting at COM10.
Anybody got solution for this? btw, no USB hub. I got 16 USB slots on my pc.
Windows 8 is able to find 1 USB Erupter. Testing on my Windows XP laptop tomorrow.
