Well, correct me if needed, but I think USB gadget is basically using a
Linux host as a USB *device*, not a USB *host*. So, unless you're doing
embedded (or working with fairly specific hardware), it is probably not
what you want.

And if it really is what you want, well, a USB tracker (keep track of
packets) could be a good starting point.
