The kernel provides a device node for each of your USB devices, but you
aren't really supposed to interact with those using the standard Unix
utilities.  They're used by libusb, which makes it possible to drive
USB devices directly from user space.  For instance, sane's USB scanner
drivers use libusb, and libusb communicates with the kernel via device nodes
under /dev/bus/usb.  I don't know much more about how libusb works
internally.  My understanding is kind of sketchy.

So what I'm saying is that those device nodes are only of interest if
you wanted to write a user-space programm using libusb to directly
interact with the TripleTalk.
