the '002/006' part is "bus->dirname, dev->filename" in libusb.c.

Does anyone know where to get the directory prefix from libusb (e.g.
/proc/bus/usb, /dev/bus/usb)?

I was thinking that it would be helpful for debugging permission
problems if we could post the complete path to the USB device node.

If not, we could tweak libusb's debug level when the library is
initialized ("usb_path" is a static var that is printed in linux.c in
libusb).

Thoughts?
