With MinePeon, does anyone know of the USB Block Erupter ASICs will work 'out of the box'?

Thanks for the help  Smiley

They won't work out of the box on the version that is released as of today. I was able to get the current version of bfgminer to run on it but not cgminer.

I posted more on it here: https://bitcointalk.org/index.php?topic=137934.msg2345214#msg2345214

I didn't have any luck with cgminer either. I had a little raspberry pie and the Anker 3.0 USB hub, and I heard the Anker could have been the problem though. Waiting for a new version of cgminer and a new hub to arrive - keeping my fingers crossed!

The Anker hubs definitely do not work with the PIs. I picked up 5 of them which I have to return because I want to go pure PI based. They partially work and look sexy. On a USB 3.0 machine they work great though.

This is the hub I would recommend.

The ports look too close together for Erupter sticks.

Oh yes. I definitely need to mention that =) These can only power 5 sticks. I burned two of them out trying 6 and 7 sticks.

Also, block erupters USB run way to hot for not external cooling so don't stress the closeness to much. Its mandatory you cool these or they hardware error through the roof.

I have bfgminer working on minepeon - had to compile from git, the one installed by default does NOT work.

I posted some instructions and such here https://bitcointalk.org/index.php?topic=220905.msg2326740#msg2326740

I have it working on a Pi running cgminer 3.1.1 (on Raspbian).  I had to specify -S /dev/ttyUSB0 etc.

I did not have any luck with cgminer 3.2.0 (yet), or with 3.1.0.

I did not try MinePeon.

I'm using Rosewill 10-port powered hubs.  They seem to have no problem powering 6 or 7 sticks (7 on 2 of them, 6 + the Pi on another).

i've got this Rosewill hub on the way... good to know you've got yours to work!

it's a 3.5A, so i think 7 erupters would be a hard limit Smiley

Thank you for this important piece of information. I have ordered one of these through an American user of this forum. Looks like I'll have to try something different.

Worth noting I have 80 units running 5 per hub on the hubs I mentioned above.. several days now with no problems after I downgraded from 7 to 6 to 5.

What is the range of hw errors as a percent of accepted shares that you're getting, please?

On my working one it is running at about 0.9%. (IIRC, several other folks have reported getting about a 1% hw error rate.)

One which is now dead and in the process of getting replaced ran at about 10% hw errors for roughly eight hours. Then it died.

NOTE: I had a fan blowing over them. They were both 'warm to the touch'. Not the 'freaking hot' you encounter without active cooling.

Anybody running BE USB devices *and* Cairnsmore CM1s on Raspbian and MPBM.

That combination crashes the machine when I tried it.

How many Erupters can Pi handle?

Without a hub? probably none.

A single PI can handle 45 block erupters decently well. If you view my profile and click on view posts I posted about this with screenshots in a couple times.

You burned out the block erupter or the hub??

Burned out the hubs. No problem at all with 5 sticks though. Been running 5 per hub for several days now with no problem at all (external cooling - 80 total).
