Comment on Will there be power issues if I plug an unpowered USB hub into a powered on or vice versa

T156@lemmy.world ⁨10⁩ ⁨months⁩ ago

will the unpowered hub run into power issues if I plug high-power-consuming devices into it?

Yes, since it’s limited by how much power it can draw from the other hub, and would have a limit on how much power the unpowered hub can pass to its own ports.

And does it make any difference if I switch the hubs order?

Yes. Putting the powered hub second means that it doesn’t need to pull power through the unpowered hub, and it should be fine right be used as normal.

I might be misunderstanding, but wouldn’t this still be a problem?

  Why would the first be a problem? The powered hub doesn't get the power from the power hungry device from the unpowered up, does it?

  Just plug the lower power device in the unpowered or powered hub from the first example. You’re just adding a hub for no reason.
