Can only control two charging ports on Plugable USB3-HUB7-81X #378

Closed mtfurlan closed 2 years ago

mtfurlan commented 2 years ago

I have a Plugable USB3-HUB7-81X and I can only control power on the two charging ports, same as the Plugable USB3-HUB7C.

Do you want me to email plugable and try to see if they ever changed it, or do we just assume all USB3-HUB7-81X only work on the charging ports?

Well, it does not hurt to ask :-) Certainly, ask them please!

To my knowledge there was no change during the manufacturing of that USB HUB. Typically when a change is needed for the electronics from a device, we will do a relaunch as a new product so that the support for our products remains clear.

They suggested the usbc-hub7bc as the only plugable USB hub that had full PPPS, and that is already in the list.

For me, usbc-hub7bc is not referenced into to uhubctl readme, there is only the USB3-HUB7BC. https://github.com/mvp/uhubctl

Did you have one usbc-hub7bc in stock to test it ? this model is pretty recent (2021.07)

I now have a USBC-HUB7BC, and 6/7 of the ports work. I've opened another ticket with them to ask if that's expected.

Port numbering left to right:

I also received my Plugable USBC-HUB7BC today, and I can confirm 6 or 7 ports are working with uhubctl ! @mvp : you can add it to readme :+1:

port1 = 3.3 port2 = 3.2 port3 = 3.1 port4 = 3.4 port5 = 2 port6 = 1 port7 = no PPPS

For USBC-HUB7BC, last rightmost port also can be disabled (VBUS power also gone) by disabling the Port 3 of 1st "4 port subhub": uhubctl -l -p 3 -a off BUT There is an issue with that... :) Because port 3 is also used to daisy-chain the 2nd "4port subhub", the 4 leftmost ports will be gone from the system (VBUS still ok, but no data)!!
