Title: [WTB] True 7-port USB hub Post by: Luke-Jr on October 16, 2012, 08:56:00 PM Many (most?) 7-port USB hubs on the market seem to be made up of two 4-port controller chips internally (with the 4th port on the 1st controller connected to the upstream port on the 2nd). Since USB has a 5-hub chain limit, this adds up fast. I'm looking for a 7-port USB hub that is built on a true 7-port USB controller chip. Unfortunately, I haven't managed to find out which those are.
As far as I know, the only controller chips that support true 7 ports downstream are:
I presume such a USB hub will also appear to the computer (lsusb on Linux, at least) as a single USB hub, and dual-4-ports as two USB hubs. Information is welcome (eg, models that are true 7-port hubs), as well as offers to sell such a hub. Bonus for something I can use for charging, and/or working per-port power switching (this lets your computer turn each port on/off). Thanks, Luke Title: Re: [WTB] True 7-port USB hub Post by: Luke-Jr on October 17, 2012, 02:14:23 PM Here's some lsusb that seem to be relevant:
