low accepted shares on 1 out of 3 ASIC Miner

[ve]

Hello

I am running windows 7 cgminer 3.1.1 with 3 ASIC Miner running at 335 mhz on slush's pool my hash rate on the pool is one 466 mhz from some reading i understand that its show of the hash rate of accepted share is this correct? but I have noticed one of my cards are getting very little accepted shares but no rejected or hardware errors I am running from a bat file

cgminer-nogpu.exe -o stratum.bitcoin.cz:3333 -u xxxxxxxx -p xxxxxxxxx --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COM3 -S COM5 -S COM6

either the hubs not providing enough power or a faulty miner try each miner on its own to check they all work. let them run for 5 mins. if they all work and get plenty of accepted shares then its a hub problem
