For test: if I replace the entire drivers/bluetooth subdir with that of kernel
5.9.14 and recompile, then it works again.

This means that it depends on some modification introduced.

The problem seems to be this commit:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/bluetooth/btusb.c?h=v5.10&id=b40f58b973865ee98ead884d2bdc7880b896ddb8

"Bluetooth: btusb: Add Qualcomm Bluetooth SoC WCN6855 support"

Removing this commit solves the problem (for me).

Same here.

With 5.9.16 it works fine

Glad it did. I'll see if this fix will be implemented. Otherwise I'll stick
with 5.9 till I'll be forced to update :)

fix hci0: don't support firmware rome error

Avoid returning error code when bluetooth version match is not made from
qca_devices_table and version high is set.

This reverts an error check that was removed to support WCN6855 which does have
the high version set. The fix is to move the check after the table is scanned
and no version match is made.

This fix will still produce the error message for example (for ATK3K 13d3:3402
IMC Networks Bluetooth USB Host Controller)

Bluetooth: hci0: don't support firmware rome 0x1020200

But the bluetooth hardware still works as it used to

Several people have reported that since b40f58b97386 ("Bluetooth:
btusb: Add Qualcomm Bluetooth SoC WCN6855 support") they have issues
with their Bluetooth adapter stopping working. It was reported at
bugzilla[1].

Bradley Jarvis posted/attached a patch which seems to resolve the
issue, Moreno has added an alternative patch.

 [1] https://bugzilla.kernel.org/show_bug.cgi?id=210681

But there is another report at

 [2] https://bugzilla.kernel.org/show_bug.cgi?id=211571

and that last one was applied to bluetooth-next tree according to
https://lore.kernel.org/linux-bluetooth/CA2C8796-11CA-4E6F-A603-AE764516C850@holtmann.org/

I have tried it (kernel 5.10.3), I confirm that it works.

Can confirm on Debian Buster as well.  Upgrading to 5.10.4 on Testing causes
Bluetooth to fail to enable, reverting to 5.9.15 on Backports solves the issue.

It would be very nice if there was a way to fix this not involving recompiling
the kernel.

$ sudo pacman -U linux419-4.19.169-1-x86_64 .pkg.tar.zst and reconfigure

All kernel below 5.10 works well. You dont need to use 419, you can use eg 5.9.
Also if you are using manjaro you can just use MHWD or pacman -S to manage
kernels

Can confirm that this issue exists on fedora 33 5.10.x kernel for atheros usb
bluetooth.  Installing a kernel.org kernel with Bradley's fix solves the
problem.
The adaptor shows up as Lite-On Technologoy Corp: Bus 001 Device 004: ID
04ca:3006 Lite-On Technology Corp.

Has anyone send a (direct) email to Rocky Liao, the author of the troublesome

this?

That is likely the fastest way to get this resolved.

Like Bradley Jarvis' fix, but it won't produce an error message but a warning
message for a possible incompatibility. Reverted the "don't care" comments for
other high ROM versions. Just my 2 cents

Several people have reported that since b40f58b97386 ("Bluetooth:
btusb: Add Qualcomm Bluetooth SoC WCN6855 support") they have issues
with their Bluetooth adapter stopping working. It was reported at
bugzilla[1].

Bradley Jarvis posted/attached a patch which seems to resolve the
issue, Moreno has added an alternative patch.

But there is another report at

 [2] https://bugzilla.kernel.org/show_bug.cgi?id=211571

and that last one was applied to bluetooth-next tree according to
https://lore.kernel.org/linux-bluetooth/CA2C8796-11CA-4E6F-A603-AE764516C850@holtmann.org/

Unfortunately it is taking quite a long time to get the fix for this into
Linus' tree and the stable rules say that only fixes which are in Linus' tree
can be cherry-picked into the stable series.

For Fedora users I've added the upstream patch:
https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=234f414efd1164786269849b4fbb533d6c9cdbbf

Fixing this as a downstream patch for the Fedora kernels. So this should be
fixed in the next F32 and F33 kernel builds, which will likely be the 5.10.18
builds.
