| libusb headache First post, so do be gentle.  I am trying to get libusb to work w/ my compiler and all seems fine until I try something like: Code: #include <usb.h>
int main(int argc, char **argv) {
struct usb_bus *busses;
usb_init();
usb_find_busses();
usb_find_devices();
busses = usb_get_busses();
return 0;
}

| Sometimes these things require additional options to gcc, as with gtk+ and pkg-config. I've never used libusb tho, so I don't know.
