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.

*-usb:3
                   description: Bluetooth wireless interface
                   vendor: Intel Corp.
                   physical id: a
                   bus info: usb@3:a
                   version: 0.00
                   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.
