Trying to use Block Erupters with Ubuntu 13.04 I'm trying to Mine with ASICMiner's Block Erupters on Ubuntu 13.04. I've installed everything (bitcoin-qt, cgminer, bfgminer, I've got the block erupters in usb hubs hooked up to my ubuntu box).

But neither CGMiner, nor BFGMiner detect the block erupters...

When I go to /dev I see 18 ttyUSB[0-17] devices, I guess that's probably them, but I don't really know how to tell if my system can even see them.

I have the hubs they're plugged into hooked up to another usb hub so that you've got the first hub coming out of one usb port from the box and the ANKER hubs that hold the block erupters are both hooked up to that. I don't know if that's messing it up.
to determine if they're being detected properly, use the 'lsusb' command. 

Here's what they should look like if your system is detecting them properly (I run mine in a VM running Ubuntu:

$ sudo lsusb

Make sure they're detected by the miner by using sudo bfgminer -S all -d? -- I found this to be a lot better on linux than cgminer. 

Then start your miner with sudo bfgminer -o $pool.goes.here -u $USER -p $PASSWORD -S all
