MicroLite USB Bandwidth Help?

Hi,
I'm using a MOTU Micro Lite USB-MIDI Interface with a 2013 MacMini and AbletonLive.
I have it running into a powered USB Hub, then into the back of the Mac.
(I learned a long time ago that using an unpowered hub was causing all kinds of issues)
I've noticed that sometimes when plugged in, or when I open up an Ableton project, the MIDI doesn't respond and I have to unplug it and plug it back in (sometimes a few times) to get it to respond.
This seems to happen more often when I have any other USB device plugged in (ie, a 32GB flash drive)
So I guess I'm wondering how much bandwidth (for lack of a better word) I can get via a USB port VS how much is required by the MOTU Micro Lite to function properly... and if there is any way to ensure its getting the power that is required (for performances, etc). maybe getting a splitter cable of sorts and splitting it into 2 USB ports?
It looks like maybe I can see in my 'system information'/ USB Device tree, whats plugged in and how many mA's it's using vs the allocated 500mA per port. maybe?

I should also mention, I've noticed using more than 2 ports causes MIDI issues as well. Random notes here and there, sync issues, weird stuff.
So I'm having to cram all the drums, synths, guitar pedal MIDI info, etc. into 2 Ports with many different channels.

Bandwidth is how much data can stream. Your problem is power consumption. See if the problems go away with external power.
