Stated cap
Every receiver takes a USB-A port
Each receiver fits, works immediately, and takes a port with it. The arithmetic only fails at the moment there is nothing left to plug the last one into.
What each node contributes
The machine ports · decides this
How many USB-A ports a machine has is not stated by any laptop listing in this catalog. It is a countable fact about the machine in front of you.
The receivers
Each 2.4 GHz receiver occupies one port. Wired devices occupy one port each as well.
The devices
A receiver from one manufacturer is not stated to work with another manufacturer’s device unless the listing says so.
Why it looks fine on the page
Wireless is the word on the box, and the receiver is a fingernail-sized thing that disappears into the side of the machine. Two of them is a shrug. Four wireless devices on a laptop with two USB-A ports is a problem that appears fully formed on the day the fourth arrives, and every individual purchase along the way was correct on its own terms.

What is actually limited here
The number of USB-A ports on the machine, which no listing in this catalog states.
What to check instead
- The number of USB-A ports on the machine, counted by looking at it.
- Which of your devices state a receiver, which state a pairing, and which state both.
- Whether a device that states both routes could take the pairing instead and give a port back.
- Whether a receiver is claimed by its listing to work with another device, rather than assumed to.
