My LT had the 7" MyLink and single USB port in the front. For those that haven't noticed the 7" MyLink source menu has USB1 and USB2, where USB2 is always grayed out. This is because USB ports hub in pairs and you only have one. That MyLink is begging for another port.
While I had a LT w/ 8" Mylink loaner I decided to pop out that dual USB module and compare with the module in my car. Both connect with a miniUSB connector and separate 5V power connector. I ordered part 13509942 ($32 bucks at my dealer, $50-70 online), popped out my single port module and installed the dual port module. Both ports now work, USB1 and USB2 can be selected. My goal was play music off a USB and charge a phone separately or charge two phones. Works.
The current part number seems to be 13519224 but it wasn't around when I made this little guide.

Procedure:
1) Car off, key out and away from car
2) Locate USB module under radio. See photo:
3) Using small flathead screwdriver (smaller the better) insert into middle of left side of module, push in then pull slightly.
4) Repeat on right side of module and extract entire module. See photos and picture of the module out of car:
5) Push tab on miniUSB connector to remove
6) Push tab on 5V connector to remove
7) Install both connectors (just push into place, they only fit one way) on replacement module 13509942. See pictures of old and new module connectors:
8) Reinsert module by just pushing until it clicks into place
9) Turn on car and enjoy your replacement or 2 USB ports in a previous 1 port car. See photo:
This worked on my LT w/ 7" MyLink and a LS w/ 7" MyLink
Works on 2016 and 2017 gen9 Malibus with 7" Mylink. USB ports are functional, AUX port is not
DOES NOT work on 2018 Malibu; they changed the MyLink software and it limits one selectable port
