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
If I'm starting cgminer only with -n it outputs this:
sudo ./cgminer -n

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 ?
