Bug 215167 [1] reports a regression in Linux 5.14, and the referenced
openSUSE report says at the end it should be fixed in 5.16.1.

Nickolas, thank you for attaching the full Linux logs. As the error from
the bug title is not present in the log, I recommend to close this
issue, and create a new one for your problem with a descriptive title
like *Bluetooth only starts working after reloading btusb and btintel*,
attaching all the files there. If you could bisect [3] the commit, that
would even get you there faster. The Bluetooth device can even be passed
to a virtual machine, and if the problem is reproducible there,
bisection is quite fast [4][5].

I am sorry about this, but unfortunately, the comments by others on
probably different issues, make it very hard and time consuming to
understanding the actual issue. It looks like the maintainers are
overworked and the subsystem has not enough resources. Still if you buy
a device with Intel hardware (and even better a device with official
GNU/Linux support), it's valid to expect that Intel hardware works also
on GNU/Linux.
