Help with AntMiner U3 and cgminer...

Hi,

I'm mining for fun and software development and I'm having a problem with cgminer

I've grabbed cgminer, installed pre-reqs and compiled:

linaro@bitseed:~/$ git clone http://bit.ly/1GbOmKH linaro@bitseed:~/$ cd cgminer/ linaro@bitseed:~/cgminer$ sudo ./autogen.sh linaro@bitseed:~/cgminer$ sudo apt-get install libcurl4-openssl-dev linaro@bitseed:~/cgminer$ sudo apt-get install libudev-dev linaro@bitseed:~/cgminer$ sudo ./configure --enable-bmsc linaro@bitseed:~/cgminer$ sudo make 

No problems here... then I try to run (with a valid address):

linaro@bitseed:~/cgminer$ sudo ./cgminer --bmsc-options 115200:0.57 -o stratum.mining.eligius.st:3334 --bmsc-voltage 0800 --bmsc-freq 1286 -O <address here> [2015-10-12 22:28:36] Started cgminer 4.9.0 [2015-10-12 22:28:36] ---------------------start voltage---------------------- [2015-10-12 22:28:36] Send voltage aab800c0 [2015-10-12 22:28:36] Send voltage ok [2015-10-12 22:28:36] -----------------start freq------------------- [2015-10-12 22:28:37] Send frequency 82128614 [2015-10-12 22:28:37] Send freq getstatus 84000400 [2015-10-12 22:28:40] Recv 1 freq getstatus=802501020a [2015-10-12 22:28:40] Recv 2 freq getstatus=802501020a [2015-10-12 22:28:40] Recv 3 freq getstatus=802501020a [2015-10-12 22:28:40] Recv 4 freq getstatus=802501020a [2015-10-12 22:28:40] --------recv freq getstatus ok finish--------- [2015-10-12 22:28:41] -----------------start nonce------------------ [2015-10-12 22:28:41] Bmsc send golden nonce1 [2015-10-12 22:28:41] Bmsc recv golden nonce1 0345182b9f -- 0345182b [2015-10-12 22:28:41] Bmsc send golden nonce2 [2015-10-12 22:28:41] Bmsc recv golden nonce2 466b30a59f -- 466b30a5 [2015-10-12 22:28:41] Bmsc send golden nonce3 [2015-10-12 22:28:41] Bmsc recv golden nonce 857e65ee9f -- 857e65ee [2015-10-12 22:28:41] Bmsc send golden nonce4 [2015-10-12 22:28:41] Bmsc recv golden nonce c6f702849f -- c6f70284 [2015-10-12 22:28:41] AMU0 Init: mode=default read_time=57ms limit=0ms Hs=2.976100e-09 [2015-10-12 22:28:41] Probing for an alive pool [2015-10-12 22:28:42] Pool 0 difficulty changed to 512.0 [2015-10-12 22:28:43] Network diff set to 60.8G *** buffer overflow detected ***: ./cgminer terminated 

Everything seems to go okay, but as soon as I get some work cgminer dies!

I've managed to compile and run using --enable-icarus instead of --enable-bmsc, but everything I read says I should be using --enable-bmsc. My hash rate was also slower than expected when using icarus.

Has anyone experienced this before?

Thanks!
