Tom,
Honestly, your best bet is to update the old scripts to use the UHD
interface. It's not a very big switch between the old and new; really,
it's mostly syntactic changes. Also, to be blunt, there is a way to
use the old libusrp drivers, but if you aren't experienced enough to
update to UHD, trying to mix and match the old libusrp with new GNU
Radio is also going to be difficult.

My suggestion would be to go into GRC and create just a simple UHD
program. Just drop down a UHD source and drive it into a GUI sink.
When you build/run this script, you can look at the build Python for
the syntax you need to copy over to your old scripts.

Hope that helps.

Tom
