I have 4 U1's but I consistently have problems getting them to hash even at a consistent 1.6 Gh/s. I've tried OC'ing but the hash rate just drops to around 1 Gh/s or below. Do I need to cool them or just a better hub? I've got one attached to my laptop's USB port and 3 on a Belkin 7 port, powered hub.
I'm using the newer BFG Miner posted on this thread.
Any help is appreciated.
some dude in this thread had a similar prob , think he was using the old bfg tho , he couldnt get the cgminer to work the first time, but ended up getting it to work and problem solve for him.
