hi
i did not have any issue with my bluetooth card before a major update a few weeks ago , after the update i noticed that the bluetooth icon no longer appears on my task bar , i go to settings and click on enable but nothing happens, hovering over the bluetooth icon in the “show hidden icons” menu showed “no adapter detected” but now i don’t even have a bluetooth icon even in the hidden icons window.
here is my system info:

what i have tried so far:
-
i have installed bluez and bluez-utils from pacman
-
enabled bluetooth from terminal using sudo modprobe btusb then sudo systemctl start bluetooth
-
installed blueman bluetooth manager
nothing seems to work. it gets even more strange when i check the bluetooth service log using sudo systemctl status bluetooth -l
