Your screenshots still showed a lot of hardware errors. How are you powering the Antminer? You're not using the Pi's USB port without a powered hub, are you?

nope. Did some research I am aware that the usb miners are amp hawks. Here my setup the usb supplies 2A and the usb and a wireless dongle are the only consumers on it the big fan runs over a seperat usb cable i soldered to a old cellphone charge cable. Was reading that the pi got enough power of itself and not to suppy other devices with it http://s27.postimg.org/96820mgan/IMG_20140406_132736.jpg

If none of them helps, it is possible that you have a bad stick. If it works directly (with another computer), but not with the hub, then your hub is likely faulty.

ok I will check that out the USB hub is a cheap on so I start with that. I just wanna make sure that the config is ok as is. http://s26.postimg.org/92fkd6gk5/IMG_20140406_135500.jpgSo many people in the web are just assuming and guessing I was reading thru the readme and made the jump in the cold water by getting the newest version where other people say dont get the new one stay with 3.1.1 because everybody is using that one. Please let me know if u want me to add or remove more from the config file. Thank you very much to both of you and I keep u posted about the usb hub results

If it's a cheap hub, especially on a Pi, that's probably it. I am given to understand the the Pi is picky about hubs. As I understand it, there isn't any config that is needed on the new Antminers, but I also use BFGminer because of MultiMiner (sorry ckolivas), so my config isn't completely translatable to yours.

ahh ok awesome I put down the clock level from 250=2GH/s to 225=1.8 GH/s and the HW errors droped from 70 after 15min mine run to 3HW error after 15 min run... Can we now automaticly point our fingers at the USB Hub and say "BAD USB HUB" or is that not prove enough to blame just the hub for th errors. As I understand, more gh/s more needed energy?

Please let me know if u want me to add or remove more from the config file. Thank you very much to both of you and I keep u posted about the usb hub results Personally, I never use *.conf -- I always use *.bat files or *.sh files to run CG/BFG-Miner. You should be able to call a *.sh file on PI with terminal. Just input your commands, save as .sh, right click - properties - allow executable (or +x chmod), then run that file. First rename or .conf so it doesn't use it. I know 3.1.1 still has Scrypt support and that is one main reason why people still use it. I am 1 step from compiling and testing the newest CGMiner if it wasn't for MingW and windows ridiculous dependency linking structure. - Create New Text-File
- Save As Name.sh
- Set Executable
- Move into CGminer Root or put the address of CGminer root in the first line
- ./cgminer or cd /home/use/cgminer/
- If -or- then type below it ./cgminer
- Your next line will simply be your input command line
I've been working on a Linux program to organize *.conf files for mining different coins and using different settings. It gets messy when you have 20 *.sh files or 20 *.conf files.

Unfortunately, no. There could be any number of reasons for low power. I've had hubs that didn't like to give good power to certain ports. It could also be bad voltage regulation on the miner itself. The only way to be 100% certain is to take the hub out of the equation. Also, yes, .bat files are the way to go.

yeah I was reading that alotof people do that . It's just that Ijust started with this kind stuff. I orientated myself on the adafruit raspberry pi mining tutorial in conjunction with the PiMiner for the 6x2 display. They worked with config. files nice and need in autostart no monitor needed. I liked that idea so I basiclly stayed on that path. Try to not get to crazy confused by all this;)

While that's probably an acceptable error percentage, since you're underclocking, you should probably be seeing none, especially in light that I have 16 right now overclocked to 2.4 with no errors.

I have raspberry pi with minepeon (MinePeon-0.2.4.6-RaspberryPi.img).
Installed it into a sd card, and i use browser to access minepeon.
I have to antminers U2 connected in an usb hub to the raspberry pi.
I have a question.
The 2 antminers U2 are mining, but they are using default bfgminer.
I would like to know if you recommend me better to use cgminer, and where can i find a tutorial for installing it.
I just installed last minepeon version for raspberry pi, and then just setup the pool url with user and pass, and its mining, but i dont know if its better to use cgminer or not.
Thanks!

In my experience, there is no significant difference between the two insofar as performance is concerned. Your only differences will be features, and for your needs it doesn't sound like it matters.

Hi. Is there a tutorial of how to overclock this antminer U2??
+1 i have 2 antminers U2+ and would like to know(in linux), with my raspberry pi, what command line do i need to overclock them. Right now, they work without overclock at 1.95GH/s. and would like to increase it a bit, without damaging the antminer. thanks

That ancient version has no support for antminers anyway. It thinks they're block erupters and probably runs them at ~500MH.

oh and here for the record the overclock settings. A noob (me) did some homework
ohh commandline for BFG is on the end: antminer:clock=xValue (no space between x and value) and then after the x the value for the clock rate 1.6=0781 1.8=0881 2.0=0981 2.2=0A81
For CGMiner newer Version --anu-freq Value (space after freq) 1.6=200 1.8=225 2.0=250 2.2=275 2.4=300
