I have one U2 (3 more coming) running on an ORICO P10-U2 10 Port External USB HUB Ultra Mini USB HUB for Laptop & Desktop (10 Port HUB with Power Adapter) and I have yet to consistently hash above 1.5Gh/s.
I have it overclocked (I thought) –set-device antminer:clock=x0981, using bfgminer and btcguild for my pool. What is causing it to under perform?

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

Have also U2 running.
Have command:
-G -S antminer:all --icarus-options 115200:1:1 --icarus-timing 3.0=100 --set-device=antminer:clock=x0981
That works fine for me, with the x0981 they run after ~ 15 min. exactly at 2,0 GH/s
My tests with command x0A81 to overclock to 2,2 GH/s work with 3 USB-miner, with 4 USB or more they tilt. But at 2,0 GH/s with x0981 i can let work 6 sticks same time.

Edit:- On BTC Guild- settings configure the worker for the USB Miner at difficulty 4.
- With 3-4 U2 set difficulty at BTC Guild- settings at 8.
- With 5 or more U2 set difficulty at BTC Guild- at 16.
- They have some minutes to arrive at good GH/s, first 1 - 5 minutes they run unstable
Edit 2:
Do you have a cooler? A fan? If you overclock, (2 GH/s or more) it is needet, so they run stable. Without cooler they often have 20 - 30 minutes stable, then the values start to decline... under 2 GH/s

Got it working like it should!! Downloaded the newest bfgminer and created a bat file shown below
-u username -p abc -s 30 -S opencl:noauto -S erupter:all -S antminer:all -S amu:all --set-device antminer:clock=x0981
hashing over 2 finally and accepting shares like crazy. Now if the other 3 will get here i'll be good to go. Thanks for the input

I have a few of these Antminers, here are my setting in the .bat file for bfgminer, I get a steady 2gh/s with this setting.
bfgminer.exe -S antminer:all --set-device antminer:clock=x0881
