I am running now 2 blades each with own cp2102 connected to easy usb hub with cgminer 4.7.0 at avg 92GHs / 108W (really not bad 1.17W/GHs) with 0.6% pool rejections.

are you running bitmaintechs branch? if yes, could you try this: sudo ./cgminer -c pool.conf --bmsc-options 115200 :0.55 --bmsc-freq 0881 right now, if my assumtions are right, your running the timing at 100ms which means your not reading the chips fast enough, therefor loosing a few GHs, in the same power usage. edit: of course i forgot to order any solder paste... doh! so ill have to wait until it arrives...

we need to read the chips fast enough for when the chips have anything to deliver, but not too fast to waiste time, and chip speed, so its a tradeoff.. the timings are the same as those found in the antminers config file versus speed.
edit: on my test board with 200MHz and timing 100 vs timing 55 60 = aprox 5 GH lost if read to slow

even better with 0.44 - 93-4GHs/106-7W

If I will be able to make cheap and easy box I will buy some blades and build unit, but only if get consumption low enough edit: but it would be very difficult to get better then 1.17W/GHs... so...

impossible just happened... 104GHS/109W 0.44 0781 edit: pool rej. 1% theoritical it should be possible to get 100 GH vs 90 watts but depends on resistor setting and psu

I thought I'd missed something you put out earlier! Thanks for the pointer. I managed to compile having made the changes to driver-bmsc.c, aka replace memcpy((char *)&nonce, nonce_bin, sizeof(nonce_bin)); with memcpy((char *)&nonce, nonce_bin, sizeof(nonce));Then issued: ./autogen.sh --enable-bmsc CFLAGS="-02 -Wall -W -march=i686" --host=i686-pc-mingw32 make I did NOT include driver-icarus as has been suggested somewhere else, and the device was detected albeit with some issues. Below are the two screen shots i grabbed: EDIT: I run the executable with the options: --bmsc-options 115200:0.6 --bmsc-freq 0F81 http://s18.postimg.org/dqch8g7yh/470_Err2.pnghttp://s28.postimg.org/hqshlfj6l/470_Err1.pngExactly the same result without zadig) if zadig is installed -no USB device detected
