Absolutely not, it's accessing the dongle via libusb directly. The rewrite
was done mainly for maintenance reasons, since the old driver was a real
mess, but the new one is also a lot faster and lacks some serious bugs
(though probably has a few new ones). Another major advantage is the
ability to add support for new FTDI-based dongles without patching source
and recompiling.
