The UHD is the universal hardware driver for Ettus Research products.
The goal of the UHD is to provide a host driver and api for current and future Ettus Research products.
-Users will be able to use the UHD driver standalone/without gnuradio.
-Also, a dual license option will be available for those who build against the UHD
-but cannot release their software products under the GPL.
+Users will be able to use the UHD driver standalone or with 3rd party applications.
