Hi Melanie,
I'm Sumit, here to answer your query at the Microsoft Community.
Apologies for any inconvenience you are experiencing. I am happy to help you today.
It sounds like either the USB port or the receiver might have a defect. I assume you tried a different USB port.
Could you please test on another computer and let me know if it works?
I look forward to your reply and am ready to collaborate until we reach a resolution. Best of luck!
