RTL Driver Active - Can't Fix


I know this error is something that comes up a lot, and I have searched here, and Google, but I’m just getting no luck.

I’m on an Orange Pi (Regretting not getting another RPi), running Ubuntu 16.04. I have PiAware setup, and it’s communicated with FA, but I get the RTL driver issue;

Using device 0: Generic RTL2832U

Kernel driver is active, or device is claimed by second instance of librtlsdr.
In the first case, please either detach or blacklist the kernel module
(dvb_usb_rtl28xxu), or enable automatic detaching at compile time.

usb_claim_interface error -6

I have attempted to blacklist the drivers in /etc/modprobe.d/blacklist.conf to no avail, and I have followed another guide which rebuilds adding a flag of; -DDETACH_KERNEL_DRIVER=ON -DINSTA LL_UDEV_RULES=ON

This also hasn’t helped.

Is anyone able to help? I’ve been trying to get this myself for the past few hours, and I’m stuck now.


Note sure if this helps:

#open file rtl-sdr-blacklist.conf for editing
sudo nano /etc/modprobe.d/rtl-sdr-blacklist.conf

#add the following 2 lines to above file:
blacklist dvb_usb_rtl2832u
blacklist dvb_usb

#save file, exit and reboot
sudo reboot


Ahhh, I’m an idiot. I just realised when I came back here that I didn’t have “dvb_usb_rtl2832u” anywhere.

I’m not seeing a funy issue (I’m not near the feeder, so it may not be an issue)

But I have;PiAware and MLAT showing green, but FlightAware coming up as red saying the Pi hasn’t checked in recently. This is odd to me as it all seems good.
