PlutoSDR with RaspberryPi4 (Unable to claim interface, device or resource busy)

sudo vs non-sudo should make no difference here.

The error itself points to another application trying to use Pluto simultaneously. Do you try to create multiple object that interface with Pluto in your script or have other tools using it like IIO-Scope? Can you try using the IP address as so: 

sdr = adi.Pluto("ip:192.168.2.1")

-Travis

I mentioned the sudo and non-sudo commands because I thought using sudo, the resources would free up because of sudo but that did not work.
There is no other application using Pluto while I run my script, and the code only creates a single object.
I tried using the IP address but no luck because the interface over ethernet isn't shown even in iio_info -s. 

Running using the IP address: 

here's a snippet from my code that I am trying to run .

import adi
import time
from scipy import signal
import matplotlib.pyplot as plt
import numpy as np

sample_rate = 800e3 # Hz
bandwidth = 200e3 # Hz
center_freq = 900600000 # Hz
num_samps = 10000 # number of samples returned per call to rx()

sdr = adi.Pluto()
# sdr.gain_control_mode_chan0 = "slow_attack"
sdr.gain_control_mode_chan0 = 'manual'
sdr.rx_hardwaregain_chan0 = 50 # dB
sdr.rx_lo = int(center_freq)
sdr.sample_rate = int(sample_rate)
sdr.rx_rf_bandwidth = int(bandwidth) # filter width, just set it to the same as sample rate for now
sdr.rx_buffer_size = num_samps

The only thing that I can think of that might be occupying the resource is when Pluto is connected and the drive is mounted (the one where we can make the configurations).

On a side note, when I do the same connection as I do with Rpi in Windows, I am able to see both contexts, IP and USB as shown 

I was able to resolve the issue using this custom Linux image at Analog Devices Kuiper Linux. The image is running perfectly on RaspberryPi4 and comes with all requirement pre-installed. Would recommend using this to avoid the hassle of installing dependencies.
