The nonce errors you are ignoring mean you are losing about 36% performance. Don't use AntMiners with BitMinter until it supports them.

I was told a very similar thing (33%) on another forum.

Thanks for taking the time to advise me. Much appreciated.

Have been happily hashing away for 24+ hours on BitMinter. I ignored the messages in the log. Saying something about nonce errors.
Ignorance is bliss? Don't know what those errors were about but BitMinter is reporting a solid hash rate.

I got mine working at 1557 MH/s (1.56 GH/s essentially) by using BitMinter JAVA app on my MacBook PRO.

I had to download the drivers from http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx and reboot.
Prior to that I was only getting 300-something MH/s via Asteroid.

They already work fine in asteroid at 500... Using boot camp at the moment to get most of it while I'm waiting for my raspberry pi as a solution.

I was able to build a version of cgminer to get them working using Icarus drivers, but they do not run faster than 500MH/s. I'm waiting until they're officially supported, I suppose. I can't get anything else working.

Hi all - I need help building the custom cgminer to run the new Antminer U1 USB ASIC. I have attempted to pull from GitHub and build according to Unix instructions, but I'm getting a plethora of errors. Most notably, I can't even get ./autogen.sh finishing successfully. The most common error I receive is:

Code:

checking dependency style of gcc... gcc3
./configure: line 4010: AC_PROG_LIBTOOL: command not found
./configure: line 4011: syntax error near unexpected token `Windows'
./configure: line 4011: `LT_LANG(Windows Resource)'
configure: error: ./configure failed for compat/libusb-1.0

Any help is appreciated.

Hey, please let me know if you can get it to work. I also purchased an Antminer and can't get it to full speed on OSX.
Sadly, I don't know enough about coding to help you.

Thanks for the reply. I'll spin up a VM with VirtualBox and give Ubuntu a try in the short term.

Were there any specific missing libraries that I should prepare for?

I did get another cgminer working but it was only returning 0.5GMh/s instead of 1.6Gh/s per unit. I'm now overclocking them to 2.0Gh/s and so far without problems.

To get the full speed I had to compile and configure with "--enable-bmsc", this provided the full speed. I used the source as recommended from AntMiner.

I had a few errors along the way, primarily all related to missing libraries so I would advise you explore that area.

My installation was on to an old laptop running Ubuntu 12.x.

Good luck!

Cfx.

Correct, it does not work.

Only the custom cgminer provided by the AntGen team works with the device (so I'm lead to believe).

Does Antminer U1 USB not work with http://spaceman.ca/cgminer/ and http://www.asteroidapp.com/?

Just wondering why you are building a custom cgminer.
