That is why I suspect this might have something to do with
the udev rules. You can delete your own udev rule and
try run your libusb program with sudo (you still need to detach
the kernel driver if it is claimed by the kernel drivers) and see if
that works. If that works, you know the problem is with the udev
rules.

Newer version of libusb does not depend on mount usbfs
anymore, instead it uses sysfs.
