Good afternoon,
Disclaimer: New to everything related to GnuRadio.
Summary:
Receiving the following error: “fusb::_submit_urb: Cannot allocate
memory”
Using GnuRadio with gnss-sdr source block and a WX GUI FFT Sink block
(just
as a test to try to get hardware working). This is my first GnuRadio
execution.
What does this error mean exactly, and how should I approach solving it?
Expansion:
OS: Ubuntu 14.04 LTS. I am using the SiGe GN3S Sampler v2 USB front-end
with
a Garmin GA 27C antenna to gather raw GPS data for post-processing. When
executing the Gnu-Radio Companion:

I have installed all components (that I’m aware of) of GnuRadio,
gnss-sdr,
all their dependencies, and configured the drivers for the specific
front-end.
Any advice or assistance is appreciated! Much thanks!
