beeping sound from usbc-hub3p

I have 3 things connected to the hub today (but not power), and from time to time it would beep. Some times it beeps a few beeps in a row, sometimes just 1 or 2 beeps. Seems rather random too so there’s no set interval or pattern to be noticed. Do you know why it’s beeping ? Is it a problem? Thanks.

Hello Eleanor,

Sorry to hear about this issue. I’d be happy to help.

The USBC-HUB3P does not have a speaker or buzzer inside to cause the beeping so must be coming from some other device attached to it.

What kinds of devices do you have attached?

Thank you,
