Hello. I have an intel i5-1135G7 based laptop and i have a problem with
bluetooth. It disconnects at random once a day or so. The vendor is intel and
is connected via USB.

capabilities: bluetooth usb-2.01
configuration: driver=btusb maxpower=100mA speed=12Mbit/s

When it fails the message i get is:

Ιαν 10 11:41:29 mainland kernel: usb 3-10: Failed to suspend device, error -110

Sometimes a reboot doesn't fix it and needs a shutdown and turn on again to
work properly.

Thanks in advance.
