Thanks for your answer. The hub is self powered and it was weeks working alone.

The lancelot i installed today is connected directly to the rasp pi.

The problem is not the power, i think that cgminer only give works to the lancelot and the block erupter usb gets in standby...

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

Buenas Zener,

Soy de Barcelona y estoy interesado en lo que comentas. Hace unas pocas semanas que hemos formado un pequeño grupo de desarrollo. El grupo se formó desde el foro que creó Neoivan (https://bitcointalk.org/index.php?topic=166553.0).

Estamos mirando de fabricar nuestros propios Avalons y en un futuro cercano diseñarnos nuestros propios Avalons. También, con el tiempo, queremos conseguir alguna fpga de 28nm para investigar.
