Couldn't find the answer online and spent unnecessary hours trying to solve it, so I'll plop the answer here.

Problem

Software like SDR++ can't find any devices
systemctl status sdrplay shows following errors/warnings:

 <>

    
[3943]: sdrplay_apiService: UpdateDevicesL: ERROR: libusb_claim_interface() -6
[3943]: sdrplay_apiService: sdrplay_apiServiceWorkerThread: ERROR: UpdateDevices() failed 1
libusb: warning [libusb_exit] device 1.5 still referenced
libusb: warning [libusb_exit] device 1.1 still referenced
libusb: warning [libusb_exit] application left some devices open


  

Based on what I found, -6 corresponds to LIBUSB_ERROR_BUSY. The device has been claimed by something else.

Specific problem

I found this blog post on using RSP1 clone without the proprietary software: https://blog.marxy.org/2023/05/using-sdrplay-rsp1-clone-with-cubicsdr.html
It mentions blocklisting some kernel modules which capture the device.

I've been noticing some interference with Wifi devices around my house, so I started looking for a way to troubleshoot them. I've tried to use a signal scanner on my phone to see if i can pick anything up but it goes away the devices come back online before i can get out to check. After some, admittedly, brief researching, i figured i could make my own signal/frequency scanner with an SDR and leaving it out in the area i believe the interference is effecting, and recording activity. After searching around a bit more, the devices are fairly expensive for the signal range i would need, for what would amount to some troubleshooting.

Which brings me to this post. I'm hoping to not spend a decent chunk of change and this not work so I'm asking to see if anyone here has experience using an SDR (in general) to troubleshoot signals in the 2.4GHz and 5GHz range. If so, would i be able to use the ADALM-PLUTO with the 6GHZ firmware download.

The setup would consist of a Raspbery Pi with PiSDR,

I am new to sdr. Currently I have an rlt-sdr dongle running rtl_fm piped to ffmpeg. I’d like to switch to something that I can change the frequency without shutting it down and can be run as a daemon on linux, ie no tui or gui. I am having difficulty finding anything currently available.

Is there anything out there or is my only choice to modify rtl_fm to do what I am wanting?

Easily find live radio programs based on geographical location of radio broadcasters on the Internet

Smart meters form mesh networks among themselves and transmit your usage data all around. Some of them even allow the power company to turn off your power remotely, through the mesh. You might want to know if any of this information is sensitive, or if the power shutdown system has got glaring security flaws and random people could just turn your house off.

In this article, we will dive into the reverse engineering of wireless signals with off the shelf tools and how to launch practical attacks against these wireless systems.

Turbine is the SDR software for NoraSector. It's designed to capture and stream all frequencies in a trunked radio system. It is capable of decoding multiple systems concurrently, even different system types, provided they all fall within the same sample bandwidth generated by the radio and there's enough CPU available.

In this blog post I will try to explain what HRPT is and how to receive it using a cheap hardware setup based on an RTL-SDR.
