Realtek Bluetooth 5.1 Radio driver doesn't load automatically

mt flag

I have a Bluetooth usb adapter

Ubuntu 22.04.1 LTS, linux version 5.15.0-58-generic, release 22.04, codename jammy

Bus 001 Device 006: ID 0bda:8771 Realtek Semiconductor Corp. Bluetooth 5.1 Radio

I found from the installation disk that needs the drivers: rtl8723d, rtl8822b, rtl8821c, rtl8822cand rtl8761b. The driver is not detected and each time to be loaded I take out the adapter and put it back in the usb port and then finally works. How I am going to do this automatically, without plug-out and plug-in the Bluetooth usb adapter?

The only relative with the `'blue|firm'` abbreviation as highlighted text is `bluetooth` the rest are just modules.

I edited my answer. I have also a wireless keyboard and mouse. I suppose these are different Bluetooth usb devices.

Actually, I don't know how but now it works. It's not necessary to take out and put back the usb bluetooth adapter.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
