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.
I've tried to find a newer version of the BFG Miner that supports the U1's but everyone I've tried has a compile date of the 9th leading me to believe there's only one version currently out?
I've restart my U1's a few times, trying different port configurations on my laptop and I've managed to get them stable for 2.5 hours. Unfortunately the speeds aren't what they really should be - even when overclocked to 2 Gh/s. I'm hoping this is just a power issue, I have a TechNet 10-port hub on it's way with a 48W rated PSU so when that arrives I expect the U1's to perform as they should.
This image is with the '--set-device antminer:freq=0981' command which just highlights what the problem is.

Not sure if this is down to the power, BFG Miner or a mixture of the two but I've yet to test them using only one pool since I'm afraid that whatever luck has gotten the U1's to hash near their rated speed may run out and I may not get these speeds again until my new hub arrives.
