I see. The reason I did it this way was because it only took me two
hours or so to create a standalone driver from what I had before.
However you are obviously right about libusb being more flexible.

However, here's the bad news, I'm afraid I won't be able to do any
more work on it any time soon due to circumstances. When I am, I will
rewrite it as you proposed, however, this will probably be at least

If the driver in its current state is unusable for nut, I'd say just
throw it out for now and include it when I (or someone else that needs
it) makes a version using libusb.

It does the job for me for now which was the most important thing,
it's just that for now I lack the time to do a rewrite to make it
conform to the specifications.

I'm sorry!
