I'll look into this in the morning - as well as version 3.12.2, checking the NEWS file indicates that U1 support was added then (3.12.1 technically).  And thank you very much for both your patience and answers, and that goes for both of you

As far as telling the Adafruit people - I've had trouble getting support on their forums (literally zero responses to questions about these issues), which is why I started posting here.

OOOOOOOOOOH.  That makes sense.  Which version of CGMiner was that added to Icarus?

You're entirely right - I had this feeling like I was saying something but seeing something else, but I wasn't quite sure what it was - but apparently that "--enable-ants1" does do something for the U1's in CGMiner as well.  Like I said in a post above, enabling the ants1 configuration with icarus allows the U1's to hash at or just under 1.6ghz each, which is better than the 500mhz block erupter speeds I was getting before with just the icarus configured.  Also, the section below has "anu-freq" which affects U1 hashing speeds, so I think I was probably mixing those two up as far as S1/U1 stuff goes.

Also, since both miners use the same chips, I'm guessing they both communicate the same way - so maybe that's part of why the ants1 configuration is fixing the hashing issue.

If the ants1 configuration has nothing to do with the U1's, then why would the U1's be working differently with that enabled than without it?

https://www.dropbox.com/s/fvjes67wygg0ytd/CaptureCGMinerReadMe.PNG - from the ReadMe under "Building CGMiner For Yourself".  I included the URL so you could see it's kinda on the webpage with your name on it.

Can you be more specific about what info would be helpful and where I might find it?  The program which runs the LCD is in python.  I really don't know python at all, and I could go through some of the files in the package from that Adafruit Tutorial I linked in order to find that information, but I'm not really sure what information would be informative.  And as long as you're asking for more information: the screen has some push buttons that cycle through different displays - only one screen reads a format error, the others read "connecting to cgminer...", and the last display works correctly.  That last one which works, though, is just recent market prices and so doesn't rely on cgminer for data.

How about one of the older versions before the screen layout change?  Do any support Antminer U1 configuration?  I know I had to --enable-icarus and --enable-ants1 in order for 4.2.1 to recognize the U1, so I probably will try enabling all support for 3.8.4 (maybe one of the 3.9.x's) to see if I can get the U1's hash speed up - that would also be an acceptable solution.  With just --enable-ants1, 4.2.1 didn't notice they were there.  Any maybe this makes perfect sense to people here who have a greater understanding of hardware/software interaction and communication.  It has been an adventure getting this far off that tutorial and some old forum posts.

Trying to get an Adafruit "PiMiner" (http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/initial-setup-and-assembly) up and running using Antminer U1's with the 16x2 LCD Display.

I was able to get 3.8.4 to work and display the information on the mini LCD screen correctly, but the sticks would not mine over 500Mhz, I'm assuming because I could only get them to be recognized and mine with Icarus enabled.

When I finally figured out that CGMiner 3.8.4 didn't seem to have the ability to enable Antminer U1 support (or at least it didn't seem to recognize the --enable-ants1 command after trying to configure it) I decided to try CGMiner 4.2.1 - it worked and solve my previous issue of the U1's hashing at ~500Mhz.  They now hash at 1.6Ghz as they're supposed to.

The problem now, though, is that the LCD display gives a formatting error - I'm assuming because of the changes in the way the software displays its mining information the 3.x.x versions of CGminer and the newer 4.x.x versions.  I'll admit I haven't yet tried using other 3.x.x versions (perhaps one of the 3.9.x's?) to see if they have Antminer U1 support and the original format for displaying mining information - I was hoping not to have to go through each of them looking and it seems that the README on ckolivas is only for the most up to date version (I couldn't find older versions of the README, if they exist, could someone point me to them?) - is there such a version of CGminer?

I do apologize if this has been covered already in this thread, but with over 700 pages of posts I felt that posting something fresh might provide a quicker solution.  If it does, and someone knows where to find it, could you point me to the correct page to look for it on?

Thanks for your time and thanks for all the work that goes into CGMiner

I would be interested in 5 units for local pick up.

Just wanted to put in some feedback in-so-far as my experience has been good and I figured I'd share it.

Ordered a cube on February 1st, pretty late at night.  Received an email the next morning letting me know my cube had been shipped.

Cube arrived Monday (today), as it was intended to.  Opened her up, had to reattach a heatsink to one blade and re-align all the blades into their slots.  Not too complicated and actually kind of fun

Rigged my PSU to work without a mobo - easy to find guides online.  Plugged in cube and read through a couple setup guides, followed the steps, and now I'm hashing away at just under 30ghz non-overclocked.

Thank you for the product, zero-X's as promised.  And thank you again for the prompt delivery.  First experience with a group buy and it was damn near perfect.  If only Amazon and NewEgg could be this spot on
