My USB to ethernet adaptor only works if plugged into my MacBook Pro.
I tried initially using a USB expander (multi-plug) but this failed - a problem when you have only TWO USB ports!
Any suggestions?
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
Jus what "expander" did you use?
What model MacBook Pro?
This is the Mac Pro desktop forum. I requested your post be moved to the MacBook Pro laptop forum.
Thanks Illaass
My MacBook Pro is the Retina 13", 2015.
I have a Targus 4 way USB adaptor, with no alternate power source.
The same problem has just reared its head with my EHDD, although all other peripherals are working off the hub.
I guess I need to find a hub with its own power source!?
a Powered Hub is often needed for drives, and sometimes for complex devices, because they draw too much power to run properly off a passive unpowered Hub.
USB devices report their required power, and you can do the math to see. (but some manufacturers lie about what their device may need worst case, and if it says zero it will be low, but it is not really zero.)

Yes, find a powered USB 3 hub.
