Hello,
I am trying to get GNU Radio up and running, I am am experiencing an error
that I haven't been able to fix. It seems that uhd cannot find my EzTV 668
usb dongle. rtl_test, however, lists it correctly. When I try to run
uhd_fft, I get a traceback and an error that says "No device found for
----> Empty device address." I used the most recent version of
build-gnuradio to install all of the components, and have an up to date
Ubuntu 12.04 x86_64 distribution. I have also made sure that udev was
configured per
http://files.ettus.com/uhd_docs/manual/html/transport.html#usb-transport-libusb.
I have attached the outputs I get from lsusb, rtl_test, uhd_fft, and
uhd_find_devices. Please help!
I can provide additional info as needed.
Thank you!
-David
