Re: Use of USB Hub with Ethernet RJ45 Adapter

I've usually run into USB issues not with the bitrate, but with the total power draw through a single port. Particularly a problem with hubs.
Too much peak power from one port can cause device brownouts.

It's not just the max USB power spec, but the Windows power saving features that cause problems, particularly while operating on battery power alone.
I'd recommend turning off USB power saving features through the Device Manager.
