The miner I bought arrived today. It is *CUTE*. It will make a nice addition to the collection. It was a pleasure doing business with iluvpcs and positive trust was left.
The windows binary works just fine once the USB driver is installed. Too bad for me I don't normally run a miner on the few windows machines I own. I prefer to keep my miners on a raspberry pi.
Now for the bad news, and none of it has anything at all to do with the group buy. What I received is exactly what is represented in this group buy.
First of all, the linux binary listed above does not run on any of my machines.
So, I pull the source code for the modified version of cgminer from https://github.com/bitmaintech/cgminer and the fun begins.
The first issue I find is a pretty big one. The AntMiner U1 USB stick uses the same usb signature as an erupter. This does not need to be an issue but as it is right now, it is not possible to compile cgminer to support BOTH an AntMiner U1 USB and and a block erupter usb with the same instance of cgminer. Older versions of cgminer and bfgminer think it is a block erupter usb and does weird things with it.
Then, once configuring for the "bmsc" driver I run into some rather nasty compiler warnings. one is true where the code copies 5 bytes into a 4 byte storage which immediately crashes the program. The crash was disguised in a code update between yesterday and today as the device is no longer addressed so the broken code is never executed. I will spend a bit more time playing with this later but right now it appears to be a windows only solution.
Ok, going back to the windows binary only release, the device is reported as "AMU", same as a block erupter USB. Not nice. It should have its own name. Furthermore the stock "miner.php" script does not enumerate the AntMiner sticks.
So ... it is only a matter of software. The stick I have is hashing at 1.55 Gh/s on windows xp running stock. Now to overclock the sucka..

I'm up and running on Linux. Also using the modified cgminer from bitmaintech. Thanks for posting your patch to GitHub.

It compiles and runs perfectly. I made the same fix independently before finding your pull request
There's lots of good documentation from AntMiner here:
https://github.com/AntMiner/AntGen1
The cgminer command line I'm using is:
Code:
./cgminer --bmsc-options 115200:20 --bmsc-freq 0781 -u P2Pool -p P2Pool -o stratum+tcp://localhost:9332/ -D
If you aren't using P2Pool
replace username, password, and pool URL with whatever your other pool requires, of course.All my AntMiner USB devices autodetected cleanly, and I'm getting a clean 1.5 GH/s from each miner.
