Not trying to dig some old thread here, but to help others.

Am running 10 of gridseed blade using cgminer 4.3.5 win7 x64bit, and mining eth at the same time.
Basic config for cgminer:

cgminer --scrypt -o stratum+tcp://gcpool.eu:3346 -u xxxx -p xxxx --scan-serial \\.\COM3.\COM4 --gridseed-options=baud=115200,freq=850,chips=80 --hotplug 80
pause

Hope it helps.
