Reply To: How to use my RSPduo w/ Rpi-3 & command line?

First – a hearty thank you for all the work you have done with regards to the SDR universe.

I – apparently successfully – installed rtAudio, SdrGlut, sdrTest.
Unfortunately, running the following command (via SSH) gives me an error:
%./sdrTest -fc 1e6 -f 0.76e6 -am -gain 1
Detached kernel driver

It appears sdrTest is finding and trying to use my inexpensive dongle: Bus 001 Device 005: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
My SdrPlay RSPduo is attached – (from lsusb) : Bus 001 Device 004: ID 1df7:3020
but I have no way of specifying that sdrTest is to use it.
The dongle is somewhat difficult to remove since it is inside my pi radio box, whereas the RSPduo is external.

Any possibility of a workaround that will allow me to leave the dongle attached?

Thank you!
