Work fine with 0.2.2

It is because you are using a old version of bfgminer. It needs to be updated.

Why is my Hardware error so high with my Redfury:
 BPM 0:       |  2.34/ 2.34/ 2.25Gh/s | A: 754 R: 4+0(.51%) HW:3908/ 59%

Sorry, I have been playing around with the KnC driver and left it in there, it will be fixed soon.

i did git pull on /opt/minepeon/ to get cgminer 3.7.2, but it keeps trying to connect to a knc device (or driver? whatever this is) even though I don't have one. How do I stop this:

Okay so I have a USB Redfury, USB ASIC BlockErupter, and BFL Jalapeno. My minepeon is only detecting the blockerupter not the red-fury or the BFL jalapeno. How do I get it to detect them and start mining?

You need 500mA per USB.

All the Block Erupters are on powered hubs (Rosewill 5V 5A with 5 BE's and DLINK 5V 4A with 4 BE's), so they are all getting more than enough power). I see if I can find some 5V 2A power for the Raspberries.

Take another look at the Rosewill psu's, the RHB500 has a 4 amp psu and well run 8 sticks.  The D-link is 2.5 or 3amps, some early ones are the 2.5, I have one.  I have never had good luck with the D-link.  I have 4 of the rhb500 to a single PI, one hub to Pi and 3 hubs the the master hub.  3 with 8 sticks and the master has 6.  Two Pi's setup like this and they run for days.

The unpowered hub is leeching power from your Pi's.  That's why they are crashing.  Try connecting a good Powered USB Hub without backfeed between the Pi and other peripherals.  You should never use an unpowered hub directly with a Pi since it will always leech power.

You can check the reports on various powered Hubs with the Pi here: http://elinux.org/RPi_Powered_USB_Hubs

No I did not. The hub connected to the Pi is unpowered, should I still cut the red cable?

Would it be better to chain my powered hubs and then plugging them directly into the Pi?

Bitcoin Difficulty:              510,929,738
Next difficulty (estimate): 517,595,126 (+1%)

Did you cut the red wire on the usb cable that connects the pi with the first hub to prevent backpower?

My pi with 5 erupters runs fine for about a week on average before crashing.  Maybe someone can help on how to find what's causing the crashing...

Both have 5V 1000mA power supplies

The BE's may be getting enough power, but what about the Pi's themselves.  How do you have them hooked up for power?

I have been running Minepeon 0.2.4 on two Raspeberries for about a week now, and I'm still having problems with it crashing. One raspeberry will run for about a day and then crash. The other one will go for about three days before the crash.

Is there a log on minepeon to identify what is causing the crashes? I have one monitor connected to one Raspberry and I can see the onscreen error log, but I can't really understand it (not a Linux guy!).

I'm getting ready to leave the Raspberries unsupervised for about three months. Was hoping to have them mining while I am gone, but since they keep crashing I won't be able to SSH them. So once they crash I have no way to reset them. I was thinking about attaching an electrical timer that will cycle the power off and then back on once every 24 hours. This way if one or both of the raspi's are crashed they will reboot. Since I won't be shutting minepoen off the proper way will this cause problems? Any other suggestions?

The setup is as follows:

Raspberry1

2 Rosewill RHB-500 hub, with 5 USB block erupters each, 3 Dlink DUB-H7 with 4 be's, connected through an unpowered 4 port hub to the raspi

Raspberry2

2 Rosewill RHB-500 hub, with 5 USB block erupters each, 1 Dlink DUB-H7 with 4 be's, connected through an unpowered 4 port hub to the raspi connected to the raspi on one USB port,

and 2 Dlink DUB-H7 with 4 be's connected through a powered 7 port USB hub to the second USB port on the raspi

Any idea's on why the above setup is crashing minepeon? I'm sure all the block erupters are getting enough power.

hehe, yea, it's a neat show piece though... need to make a life-size Cray-2 replica with nothing but RaspberryPi's filling it... haha

I actually built one of those using 5 Pi's!  Totally useless for what we are discussing but totally cool!

I'd be interested to see if something like this is possible, more from the perspective of this being more common in the future. Lots of people hosting tiny chunks of the blockchain, bonus points if none of them have to trust each other and don't have to transmit whole blocks back and forth. Probably something for another thread though if anyone wanted to get serious about it.
