Bluetooth 5 adapter not found

Hello forum,

I changed my bluetooth 4 adapter for a bluetooth 5 adapter. The new adapter works on a Windows machine (LED on and Rx/Tx), but on my desktop there is no LED on. It just seems dead. I have tried other USB ports, and rebooted.

blueman-adapters shows:
blueman-adapters 13.48.45 ERROR Adapter:53 __init__ : No adapter(s) found
