Hi, I just received my Plugable USB 3.0 7-port hub. I’m trying to connect it to my MacBook Pro’s USB 2.0 port. Power is connected, but connecting a USB device produces only a faint blinking blue light on the port labeled 01, and nothing on port 02, 03 or 04. Connecting it to ports 05 through 07 works though. So this looks like a 3-port hub at this point.
Thanks for posting, I’ll be happy to help
When connecting a USB 3.0 hub to a USB 2.0 port, it will only be able to operate at USB 2.0 speeds. A USB 3.0 connection on the PC is necessary for a hub to operate at USB 3.0 speeds.
As to the second issue: this is a known and common behavior (ports 1-4 do not work) when the hub’s power supply isn’t connected to the hub BEFORE connecting the USB cable form the hub to the PC. A quick unplug/replug of the USB cable running from the hub to the PC should resolve this- please let me know if you find otherwise.
