I’m having trouble to find a bluetooth dongle at least 3.0 that needs no propietary firmware. It’s easy to find dongles advertised as linux compatible or users that claim that an specific brand works fine in linux, but the problem is that many of them are using propietary firmware without their users being aware because their distributions have already installed propietary drivers or firmwares, or ask users to install them and they just do it. I use debian main repository (without non-free software) in which I failed to make work a couple of linux compatible advertised dongles because debian ask me to install a propietary firmware. So if anyone knows for certain that some brand that needs no such a software in linux I’ll apreciate your help.
I do not know of any such dongle, but I’d like to ask you a question if you don’t mind: are you looking for a dongle with open-source firmware, or would a dongle that has its (proprietary) firmware stored in some onboard memory be acceptable?
The second option wouldn’t require you to install any proprietary firmware on your computer, but you’d still rely on the proprietary firmware for the device to run. And it might also exist, unlike a dongle with FOSS firmware.

what kind of computer? does it have wifi already? Its not usb but the ones I always get are the intel wifi+bt units. I bought a few wifi6e + bt5.2 recently each in different form factor for my laptop, desktop, and steam deck. apart from the deck which is soldered on and I don’t have time for yet, the pcie and m.2 wifi and bt combo cards work out of the box on bazzite.
If its a laptop or desktop that has antenna on the motherboard io panel then it probably has an m.2 card that can be swapped for a bt integrated one and you could jump to wifi 6e at the same time. or wait for wifi7 and whatever bt version will exist then I guess.
