I just got a Areneus Alea I true random number generator going with OS X. The device will work with any Unix like OS that support libusb.
First get libusb from http://libusb.sourceforge.net/ and install it like this

./configure --prefix=/opt/libusb
make
make install

Then copy the contents of the driver CD that came with the Alea I somewhere you can write to.

cd linux
#edit the Makefile and make it look like this
randomfile: randomfile.c
cc randomfile.c -L/opt/libusb/lib -lusb -Wl,-framework
-Wl,IOKit -Wl,-framework -Wl,CoreFoundation -Wl,-prebind
-I/opt/libusb/include  -o randomfile

make

Then run the resulting randomfile program to see it work. Tests with this device will follow.
