[SOLVED] Portable HDD with Powered HUB

[zilexa]

Yes, the lower port (closest to the chipset). Now I shutdown RPi, connected the hub to the upper port and booted, then rebooted just to be sure:
dmesg

Now, without rebooting or anything, while still connected via SSH, I move the HDD from the 2nd USB port to the 3rd USB port on the hub:
dmesg

three new lines appeared in dmesg:
[ 320.856449] usb 1-1.2: new high-speed USB device number 6 using dwc_otg
[ 343.637295] usb 1-1.2: new high-speed USB device number 95 using dwc_otg
[ 398.949533] usb 1-1.2: new high-speed USB device number 63 using dwc_otg
