Hello, i've a little problem, i'll try to explain.
I'm using rasp pi, and installed cgminer 3.3.1
I have 1 block erupter in a hub usb powered and a lancelot from blackarrow.

I've been using my block erupter a lot of days without problems.

Since I installed my lancelot, I tried with sudo cgminer and it starts working, but it seems the block erupter gets the first work, after that it gets in standby meanwhile the lancelot works fully. A 60 seconds the cgminer says the block erupter gets sick.

What can I do? Do you need something abot logs?

Please help!
Thanks in advantage
