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.

So 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

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.

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?

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.

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

If you're still getting a lot of hardware errors, I would try hooking it up to another computer directly, then with the hub, and seeing what helps. 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.

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?

Ok done. Is there anything else you would change to optimize the performance (add or remove)
BTW I make sure to post I to adafruit other forums and blogs as a sign of being greatful. I know you guys have to deal with alot of noobs/Beginners. After I posted in your offical CGMiner forum i saw that some people got upsaid so I was reading thru the entire readme and found the change with the clock settings;)
ohh here how it looks now.

Ok so do I just delete the entire icarus-options line outof the config or do I have to thange the value to something else

Delete icarus options and icarus timing entirely.

Hmm ok I am not a expert here and I just start playing with bitcoin stuff. As I mentioned before I use a Raspberry Pi with CGMiner Ver. 4.2.3 and one U2. So honsestly I dont have any idea what all the settings do. What I know is that I went thru alot of forums to find a answer;)

I know the numbers GH/s is high but the pool stats show only 1.3gh/s . Everybody in the web is just copies from forum to forum the same old stuff. Can somebody be so kind and explain their own settings if poss. using cgminer. The unit is cooled by a 120mm Tower fan i riped out of a old tower, cut the cable and soldered it to a micro-USB charger cable.So the unit is pretty cool.

You are using icarus options inappropriately and telling cgminer to report double the hashrate. Don't use icarus options at all, they're totally not required with current cgminer and most people use them wrongly as you have.

That's correct. Setting it to 2:2 causes it to display results 2x higher than actual. 1:1 is the correct setting. It looks like you are getting a lot of hardware errors which is causing the low reported speed. How are you powering the Antminer?

Just got mine today. I was able to get them up to 2.4 with 0% hardware errors after almost 2 hours of runtime.
They do take up two slots each on my Anker 13-port hubs, limiting me to 6 per hub (without cables).

Nice would you like to share your config file. cuz mine is not running to stable anymore. would be awesome. Run my U2 on CGMiner 4.2.3 on a Raspberry pi

Here it is after 8-10 hours:

I'm using MultiMiner with the BFGminer 4.0 beta.

Code:

-S antminer:all --set-device antminer:clock=x0B81 --icarus-options 115200:1:1 --icarus-timing long=90

If its a lot of Hardware Errors then probably need better power to the hub, if you have a good adapter check the cable to the computer.

I run with my settings (see abouve pic. 2 GH/s even (2.08239). If i use 0A81 I get a 70% Error rate...USB hub to weak? Huh

Maybe. I know that on the U1s, if you tried it without doing a voltage mod, you'd get something similar. It's quite possibly the same thing.

Yea, I've been noticing that with the Queue. The new CGminer requires you to recompile with --enable-" " strings. I'll try it later; I'm hoping to see something nice.
