description: Bluetooth wireless interface
product: AX201 Bluetooth
vendor: Intel Corp.
physical id: a
bus info: usb@3:a

capabilities: bluetooth usb-2.01
configuration: driver=btusb maxpower=100mA speed=12Mbit/s
root@zaionc:~# hcitool lescan
Set scan parameters failed: Input/output error
At first bluetooth stopped working at all due to Ubuntu bug = missing
firmware. It was fixed recently and now the bluetooth module seems
fine, but the whole BTLE part is not available. Particularly I cannot
detect/pair Logitech M720 mouse.
Platform: ThinkPad T14 Gen 2i
