TLDR Sorry if this was mentioned

I was messing around with a hub trying to figure out available watts, and noticed how finnicky cgminer is with these damn things, I could never get more than 16 running. And adding them too fast would cause a crash. Had the same problem with modminer quads. I found it alot easier to open each device in its own. here is the bat file that i use to open the prompts. Each one also will have a named window. Find the usb settings by doing cgminer.exe -n where  --usb bus:device



start cmd /k C:\besr\cgminer.exe --usb 3:50 --bmsc-options 115200:20 -o stratum.btcguild.com:3333 -u reganreckman_a2 -p 123 --bmsc-freq 0781
start cmd /k C:\besr\cgminer.exe --usb 3:51 --bmsc-options 115200:20 -o stratum.btcguild.com:3333 -u reganreckman_a2 -p 123 --bmsc-freq 0781
start cmd /k C:\besr\cgminer.exe --usb 3:52 --bmsc-options 115200:20 -o stratum.btcguild.com:3333 -u reganreckman_a2 -p 123 --bmsc-freq 0781
