Thanks for the thread. I got my Erupter yesterday but I can't get the damn thing to work :/

Here's what I have tried so far :

Plugged directly into Thinkpad X60 laptop USB (should be enough power).
Plugged into a D-Link DUB-H7 (same as pictured in an earlier post that shows it working).
Plugged into a PlusCom U7PH-3A.

When I plug the Erupter in the green light flashes 4 times then stays on.

lsusb shows :
Bus 002 Device 009: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light

/dev/ttyUSB0 appears.

Ubuntu 13.04 with http://ck.kolivas.org/apps/cgminer/3.1/cgminer-3.1.1-x86_64-built.tar.bz2 (i read v3.2.0 doesn't work) I run :

./cgminer-nogpu -o http://eu-stratum.btcguild.com:3333 -u xxx -p xxx

tried these extra options too :

--icarus-options 115200:1:1 --icarus-timing short
--icarus-options 115200:1:1 --icarus-timing 3.0=10
-S /dev/ttyUSB0
-S all

Nothing gets detected and its "Waiting for USB hotplug devices" and just idle.

I tried bfgminer 3.0.2 too and that just CPU mines as it can't seem to find it either.

I also tried MinePeon on my RaspberryPi and get no results either.

Am I being dumb, have I missed something obvious or do I have a faulty Block Erupter ? Any ideas welcome
