I'm new to Linux.
When I try to use my built-in bluetooth chipset in Huawei Matebook, the adapter seems recognized well but it could not find any bluetooth device.
I also try to use bluetooth with my dongle type adapter and then it is working
here is my hciconfig -a
~$ hciconfig -a

I wonder why it say that Bus type is USB.
and dmesg |grep [bB]luetooth
is here

my working usb-type bluetooth also fail to Direct firmware load. but it works.
nothing is blocked in rfkill list
if you want any other info, I will be glad to append
.hcd
file should beBCM4354A2-0a5c-6419.hcd
