I have downloaded the binary from OScam site (oscam-svn9112-powerpc-tuxbox-webif-libusb.Light.tar.gz) and then put the oscam file in /usr/bin with 755.
Then I put the config files in /etc/tuxbox.
When I try to manually start oscam I get this error message:
"error while loading shared libraries: libusb-1.0.so.0: cannot open shared object file: No such file or rirectory"
