Anyways, as you notice, this is an error related to UHD not finding any USRP devices.
Since we don't know which device you have, we can't help you with that. But to expedite a
solution: Guides to this are found in dozens of corners on the internet, for example

Message-ID: <661605185.819399.1692277198...@mail.yahoo.com>
Content-Type: text/plain; charset="utf-8"
I want to use the output value of a signal generator as the delay value of
a delay
block. Is there a way to pass the output of a signal generator(saw tooth)
to the
delay block? I have attached an initial grc file and a picture of what I
want to do.
Any help would be appreciated.Thanks...TomPS Do you know if I need to sign
up for
any workshops, etc.. at the GNURadio Conference next month or do I just
show up and
take a seat? I've already registered.
