I'm not so sure.
The RTL8821CE chip implements Bluetooth according to the manufacturer
(https://www.realtek.com/en/products/communications-network-
ics/item/rtl8821ce) and the above attachment Lspci.txt says:
Kernel driver in use: rtl8821ce
But then Lsusb.txt says it's running over the USB bus:
Bus 001 Device 005: ID 0bda:c024 Realtek Semiconductor Corp. Bluetooth
Radio
So I assume it's a USB device implemented on the PCIe card, whose driver
is rtl8821ce. But we can add a kernel task in case I've missed
anything...
