We already had another Anker USB 3.0 hub added and then removed in issue #49.

Are you sure that plugged phone stops charging when uhubctl turns off the power for the port?

mdhowle commented 6 years ago

They are USB SD Card readers. LED next to the port turns off, but when I plug in my phone, it continues to charge but no data connection until the ports are re-enabled.

mvp commented 6 years ago

That's what I feared... Apparently, Anker hubs lack circuitry to cut off VBUS - saved few cents...

I'm not sure what to do about such hubs. If we add them to supported table, we have to mark that they don't actually work for purpose of turning power off...

mdhowle commented 6 years ago

uhubctl works for my purpose though I see others' need for full support. I suppose adding a column stating whether a hub has full or partial (data only) support would be helpful with other with similar use cases as mine.

mvp commented 6 years ago

I think it's better to not add hubs which don't cut off VBUS to supported table.
