Check if power is being supplied by the USB ports i.e. plug in a mobile phone and check if it is charging or plug in a USB mouse and check if the laser lens turns on.
If there's no power being supplied by the USB ports, check that the ''Allow the computer to turn off this device'' setting in Device Manager is ''unchecked''.
Go to ''Device Manager > Universal Serial Bus Controllers > right click on USB Root Hub > Properties > Power Management.''
Do this for all the USB Root Hubs listed.
If the settings were enabled in Root Hub and now you have disabled ''all'' of them, restart the laptop for the change to come into effect
To get to Device Manager in Win10/11 press the Win key + x key (both keys together) and click on the Device Manager link.
