In POS we trust

maybe its a bit underpowered? I had a similar problem when I connected two Block Erupters to a 5-port USB hub with cardreader that only has a 1000mA PSU.

Ruu \o/

Upgrade to latest version of cgminer and reboot to make sure it uses the included DLL for the usb library. Older DLLs had this problem.

I tried it on Windows computer with BitMinter client and it works normally at speed of 655Mh/s Sad

P.S. I am using powered USB HUB, because Windows computer can´t handle 2 Block Erupters
