Alright PLEASE help me. This is making me go nuts and really frustrated with Linux
sudo bluetoothctlgets stuck on on "Looking for ..."
To fix this I need to run
sudo modprobe btusb && sudo systemctl start bluetooth[privileged@arched ~]$ sudo systemctl status bluetooth
[sudo] password for privileged:

[bluetooth]# exitLast time I had this problem I fixed it by adding
GRUB_CMDLINE_LINUX_DEFAULT=btusb.enable_autosuspend=n to the grub. Then I distro hopped to debian for a day to try it out and installed arch again. Same boot drive and process and as expected of the Linux operating system, Bluetooth wasn't working this time either. But to my surprise the fix that worked fine previously does not function anymore.
I have wasted around 4 hours trying the following -
Any many more answers found here as well as on stackexchange
Important things to note-
Bluetooth in BIOS (I user bios legacy) is turned on
Bluetooth works perfectly fine and right out of the box with windows. Just like everything else.
I use KDE wiith arch linux and linux kernel 5.11.16-arch1-1
