ASIC miner USB 330 Mh/sec - problem

[Africa2003]

Hi guys
I have 2 x USB ASIC units (330Mh/sec) in one PC, mining with cgminer 3.1.1
All seems to be fine apart from results in the pool's stats. It shows like only 1 miner is working (about 300Mh/sec on this miner)
However cgminer shows all is good. What could be the reason?
Thanks!

ICA0 is getting alot of hardware errors probably not getting enough power so its not atually mining much

Are the erupters in a hub or directly in the PC?

This is the problem:

LOTS of hardware errors either it isn't getting enough power or is bad is my guess.  Try running the erupters 1 at a time and see if you get the errors with them individually.  If one works and the other doesn't I'm suspecting a bad erupter.

Do you use Gigabyte motherboard?

Thanks guys...stupid me
They are in a hub which is getting not enough power I guess.
However I have new blade for 11 Gh/sec and I got them on a rock bottom price.
160 USD versus almost 300 now.
