I unloaded it then loaded it to get those log messages, but it is also
loaded during boot. I did some more digging and there is a
device, /sys/class/bluetooth/hci0, that appears once the module is
loaded, so this may be a problem with bluez.

Bluez maintainers, hci_for_each_dev in lib/hci.c doesn't recognise my
Bluetooth adapter.

        if (ioctl(sk, HCIGETDEVLIST, (void *) dl) < 0) {
                err = errno;
                goto free;
        }
        
        for (i = 0; i < dl->dev_num; i++, dr++) {
                if (hci_test_bit(flag, &dr->dev_opt))
                        if (!func || func(sk, dr->dev_id, arg)) {
                                dev_id = dr->dev_id;
                                break;
                        }
        }

While iterating through the memory filled by the HCIGETDEVLIST ioctl, it
skips over the device because the call to hci_test_bit returns 0. 'flag'
is HCI_UP. My knowledge of Bluetooth devices ends here, so I don't know
if that's a problem with the kernel, or something else in userspace not
initializing the device correctly.
