Unused downstream ports; need some kind of termination?

Post by witch359 » Fri Oct 18, 2013 5:25 am

Hi all,

I have a USB hub chip (Microchip USB2514) which has 4 downstream ports. I don't use all of them. What do I do with the unused ports?

The eval board from Microchip doesn't do anything, but their FAE says I should tie them high. He's a bit vague on the details and it's a little frustrating. Can anyone shed some light on this?

Thank you.
