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?

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

Hi there ,
I run a older version of CGMiner (will look later for the Ver. it 2:39am here). I got my Antminer U2 working with --enable-bmsc. My Pi display works prober (the adafruit one) besides that it shows 0 Devices. The U2 runs @2.032... GH/s and stabile.Because I got a vintage version of CGMiner, to which version I should upgrade???
As I said raspberry pi with adafruit 16x2 display with Bitmain Antminer U2
Ohhh ps theis program ROCKS. I am a linux noob btw

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.

I tryed to git clone Raspbian binary for 4.2.2 (called 4.2.2a) what is a executable. I dont have any idea how to do that kind of stuff. Before i just git cloned a folder do the compiling stuff (via copy/paste and thats it. How do I do this one???

I got the execute working but it gives me error no device detected icarus 1:6 failed to ini. Incorrect device

I know that I got it started as I said. But it's a executable single file. I have it setup (my current version 3.88 I think) that it runs in autostart at the moment. So I just configure the config file save reboot and Go. So Is there a clone Git link I may missed because I like to set it up the same way. 

From reading the first post in this thread, you learn you have to do this:

Go here: http://ck.kolivas.org/apps/cgminer/

If you have 32-bit Ubuntu, download the file cgminer-4.2.2.tar.bz2.
If you have 64-bit Ubuntu, download the file cgminer-4.2.2-x86_64-built.tar.bz2

Either way, unzip the file you downloaded.  Then run the executable you just unzipped, follow the prompts to set up your first pool, plug in your devices, and poof, you're mining.  (I also suggest, after you configure your pool and other settings, that you save a config file using the in-program menus and prompts.)

For anything more specific than that, you'll have to ask a clearer question.

New release: 4.2.3, 3rd April 2014


Human readable changelog:

- During network outages the devices hashrate would appear static, this has been fixed.
- Did a major rewrite of the code that writes and parses the config files. Now if you choose [W]rite from the [ S]ettings menu it should write most of the options you've given on the command line. Some options were never written correctly and many weren't written at all previously.
- Changed the toggling display to sit on the most important screen and not toggle by default, but it can be re-enabled via the [D]isplay menu.
- The hashrate line for per-device also includes the Work Utility at the end now instead of the alternate screen to better fit within 80 columns.
- Added a --widescreen option by request which does not toggle and shows all information. This can be enabled/disabled via the display menu.
- The --device and --remove-disabled commands have been removed. They are a hangover from the GPU days and choosing devices with this command does not give any meaningfully reliable way of choosing devices.
- Added checking for any number of chips on bi*fury (BXF) devices and added the extra output in the API for them.
- Hexfury USB sticks should now be detected and come up as HXF instead of BXF.
- BXF bits can now be configured on the command line in case people wish to push the maximum for hardware modded devices (normally 54).
- Solo miners can now add their own signature of up to 32 characters to the coinbase with the --btc-sig option.
- miner.php updates.
- Fixed getwork share submission which was broken for the rare pools remaining that still use it.
- Other low level bugfixes/improvements.


Full changelog:

- Decay the per device hashrates when only the watchdog is calling the hashmeter
- Fix parsing of config files failing on custom parsing
- Allow an arbitrary number of chips in the BXF driver, showing results from
each chip in the API and identify the hexfury, naming it HXF
- Disable toggling display by default and offer a --widescreen option to have
all the information on an extra wide display.
- Use OPT_WITH_CBARG for all custom parsing functions to allow their values to
be written generically when writing the config file from the menu.
- Provide a ccan variant OPT_WITH_CBARG that assigns the arguments passed as a
string and then performs the callback function on the string.
- Define strings to store special option parsing parameters leaving no
OPT_WITH_ARG missing args
- Correct the writing of special case options to the config file
- Provide support for writing anu freq from menu write option
- Update to diver-avalon2.c
- Generalise a lot more of the command line options simplifying the write config
function and making it write far more values unaided
- Use the general opt_set_charp functions for setting api parameters
- Json escape any strings written to the config file
- Store standard charp options when writing config files
- Add support for all the integer range options when writing the config file
from the menu
- Remove the --device and --remove-disabled options which don't work in a
meaningful way any more
- Make the bxf bits configurable on the command line
- Provide a --btc-sig option to optionally add a custom signature to the solo
mining coinbsae
- Compact gbt solo extra data and store the length, allowing it to be variable,
leaving room for a signature
- miner.php - Kano summary Pool Acc/Rej should be only work submitted
- miner.php add best share and gen formatting for pool summary
- miner.php - remove BGEN/GEN eval() errors from the web log
- miner.php allow optional fields when gen is disabled
- miner.php dont format missing gen fields
- miner.php make Summary a custompage
- miner.php allow uers and system lists of customsummarypages and add more
examples
- Fix getwork share submission
- Cosmetic fix to udev rules
- Put WU on the hashrate status to compact lines further
- miner.php show api/rig errors at the top of a customsummarypage

Perfect.  How wide is that?  I have my width set to 90 and it seems to display everything.
