[Discuss-gnuradio] "fusb::_submit_urb: Cannot allocate memory" Hardware integration

[DSRadin]

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!
