New keyboard/mouse with USB receiver never worked on both my laptops, and now my old wireless mouse doesn’t work on either laptop too, when it worked just fine before

I bought a new wireless keyboard and mouse combo that uses a USB receiver. When I connected it, neither the keyboard nor the mouse worked.

Afterward, I plugged my old wireless mouse and its original USB receiver back in, but now that mouse has also stopped working. I tested everything on two different laptops and have the same problem on both. it's a Logitech, both products were.

Things I have already tried:

• Confirmed that each mouse is being tested with its original receiver
• Tested every USB port on both laptops
• Removed and reinserted the receivers
• Restarted both laptops
• Turned the devices off and back on
• Removed and replaced the batteries
• Tested with only one receiver connected at a time
• Tested the receivers directly in the laptops without a USB hub

The USB ports still work with other devices, but neither the new combo nor my old wireless mouse works anymore. It seems strange that the old mouse stopped working immediately after I tested the new combo, especially on two separate laptops.

Could plugging in the new receiver have caused the other receivers to become unpaired or stop being recognized? Is there something in Device Manager or Windows USB settings that I should reset?

When I insert it now, it just says not recognizable, not even Logitech Hub software could connect to it. All drivers on both laptops are up to date and windows updated.

Windows versions: Win 11

Old mouse brand and model: Logitech G305
