I already test the usb random number generator Araneus Alea I with OSX (unix bsd).

After compiling the i found errors as below:

root:/Users/amir/linux$ make
cc randomfile.c -lusb -o randomfile
randomfile.c:16:17: error: usb.h: No such file or directory
randomfile.c: In function 'main':
randomfile.c:74: error: 'usb_busses' undeclared (first use in this function)
randomfile.c:74: error: (Each undeclared identifier is reported only once
randomfile.c:74: error: for each function it appears in.)
randomfile.c:74: error: dereferencing pointer to incomplete type
randomfile.c:75: error: dereferencing pointer to incomplete type
randomfile.c:75: error: dereferencing pointer to incomplete type
randomfile.c:76: error: dereferencing pointer to incomplete type
randomfile.c:77: error: dereferencing pointer to incomplete type
randomfile.c:84: warning: assignment makes pointer from integer without a cast
make: *** [randomfile] Error 1

I need to configure libusb to generate usb.h and other related header files.

I edit the Makefile and alter the parameter as below:
randomfile: randomfile.c
cc -I/opt/local/include -L/opt/local/lib \
randomfile.c -lusb -o randomfile

After that make it again:

cc -I/opt/local/include -L/opt/local/lib \
randomfile.c -lusb -o randomfile
randomfile.c: In function 'main':
randomfile.c:99: warning: pointer targets in passing argument 3 of 'usb_bulk_read' differ in signedness

Phew, ignore the error. Basically its no error, but warning. After successcully compile the .c file, one binary file generated called randomfile

Let test the tools:

./randomfile 1000 > random.hex

one file generated random.hex with these:
