Help with USB block erupter

[SirMintALot]

I tried bfgminer 3.2.0, and it only detects my gpu.

bfgminer didnt work because you also needed -icarus-options 115200:1:1 --icarus-timing 3.0=100 to go along with your -S All argument.

Nope, not true for the actual versions (3.14 and upwards)
all you need is -S erupter:all
The last version 3.20 also produces less hardware errors than older versions or cgminer. (cgminer/older bfgminer has usualy about 1% hardware errors with USB Erupters, with 3.20 the hardware error rate drops to about 0.6%)

if you still havnt got it working try this guide. it worked for me.

it sets up the BE's for the newer version of cgminer. this then auto detects any new miners and just runs. you don't need to define them in the miner.
