I've compiled the newest cgminer 4.4.0 with following Options on a Raspian PI Debian Wheezy:
sudo apt-get install libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev
wget http://ck.kolivas.org/apps/cgminer/cgminer-4.4.0.tar.bz2
tar xvf cgminer-4.4.0.tar.bz2
cd cgminer-4.4.0
./configure --enable-icarus
make
Done several times before with previous cgminer Versions, but with this Version I'm not able to mining. Cgminer declares that no USB Devices has been found, when I started it with following Option:
sudo ./cgminer -o stratum+tcp://stratum.examplepool:port -u xyz -p zyx --anu-freq 250
But if I'm using a previous Version of Cgminer all U1 / U2 Ants were be found, so I think that there is something going wrong with cgminer 4.4.0 ?
I wonder if it's related to the rbox code going into the icarus driver. It doesn't seem to interfere on PC linux or windows, so I'm not sure why the pi would be different but anything's possible. Does it work with 4.3.5?
