Linux Bluetooth Error : Failed to start discovery: org.bluez.Error.InProgress

Context

My Linux laptop running Pop OS! suddenly could not detect bluetooth devices anymore

And this was the error I found on the status

Failed to start discovery: org.bluez.Error.InProgress

Fix that worked for me

This may or may not work for you, but is worth a try

sudo hciconfig hci0 down
sudo rmmod btusb
sudo modprobe btusb
sudo hciconfig hci0 up
