I have a USB receiver that's for both a keyboard and a mouse. When I plug it in to a computer, it works perfectly.

But when I plug it in to my raspberry pi 4, the wireless keyboard doesn't work while the mouse works. The weirdest thing is that when I plug in a wired keyboard, the wireless keyboard works as well. This is an inconvenient solution since the wired keyboard is power-hungry.

Is there a way to tell my raspberry pi that the receiver is for both a keyboard and a mouse?
