So after researching for 4 days on why I can only get my usb hub to power only the teensy and not another usb. I came to find out a lot of truth not every usb hub is truly compatible with the pi zero so I guess I just wanna know what usb hub did you buy because I'm gonna have to get another one and want it to work when it comes.

Did you supply 5v to both the USB hub and the teensy as well as the pi? The port on the pi can't supply enough power on its own. The hubs serves to give more ports and to allow them to take more power.
If the hub you have doesn't have an obvious place to put 5v in just take the input usb and only solder the data lines (white and green usually) to the pi and hook the power lines (red 5v+ and black ground) to your 5v source.
