Mornin',

A few years ago I bought one of these cheap usb hubs:

Yesterday I added a 5V/2A (phone charger?) power supply to it which seems to work fine.

When I plug my 2Pac in it it's up to 7 times faster than plugged into the RasPi3 directly.

But when I plug in a second 2Pac this second one becomes active and the first one seems to drop in speed and the blue/white led stops flashing.

Can these cheap hubs be modded with some wiring to have more power on the ports?
