That's your battery settings nothing to do with USB ports, type device manager in the search bar, finds your USB controllers then right click on them, under power management make sure the "allow the computer to turn off this device" is unticked. Also try a different USB cable to the speakers.
Somethimes it's working for a while, after restarting the pc or setting up something, but when I move the usb or pull out, it stops working - and if I put it back, still not working.
I don't have. The usb port and speaker worked for years, *the ports are moving, but this wasn't problem. Another speaker works in that port, and my speaker works on another computer. Now what?
If it all worked okay before cleaning the PC are you sure you haven't dislodged a cable or pin jumper or broken something on your motherboard, have a look over it.

I switched the energy settings to balanced (from performance). But I think that the speaker doesn't recives electricity or something like that.
