I had this issue so I posted on StackOverflow/askubuntu (I just post this for background):

https://askubuntu.com/questions/1486016/how-can-i-turn-off-a-usb-lamp-in-ubuntu?noredirect=1#comment2602649_1486016

But I solved it myself by buying this hub:

As I explain in the question, the lamp I used is just a dumb device that receives energy, which means the power-off is a true power-off and not just a logical disconnect. I only tested one port.

@ChrisVilches, thanks for your report! Can you please test if it supports per port power switching correctly?

ChrisVilches commented 1 year ago

@mvp I was under the impression that being able to turn ON/OFF the lamp was enough to prove PPPS worked correctly. What else should I test?

mvp commented 1 year ago

Yes, turning lamp off proves vbus test is working. I am only asking about other ports being able to turn power on/off independently. I have seen some hubs which turn it off for all ports (ganged), and I want to add this device to compatible table we appropriate information. Thanks!

@mvp Yes, it only turns off/on the selected ports.

I have a Pocket Wi-Fi connected and it remains ON when I turn off the lamp.

Thank you @ChrisVilches, added this hub to compatible list.
