Can someone look over my Schematic? Answered

Hello All! I have recently started using Eagle, so please forgive the messy schematic as well as the lack of labeling-I am still trying to learn the ins and outs of the software. So I recently received my raspberry pi zeros after months and months of waiting and have been incredibly satisfied with the size and compatibility. However, the biggest issue is the lack of USB ports, which of course were eliminated on purpose to decrease the weight, size, power consumption, ect. I thought it might be useful to design and fabricate a usb hub shield that follows the form factor of the pi zero. I was searching for information and came across this IC that can serve as a 3-port hub, the TUSB2036. However, it only operates at the USB 1.0 spec. Upon further research, I found that the newer model of this IC is the TUSB2046. I made an attempt to design a schematic off known references as well as the data sheets to form a small hub for the pi zero. Can someone with electrical engineering or circuit design experience please let me know if this would work? I used this schematic as a reference and [attempted] to modify it to accommodate the four port USB 2.0 TUSB2046. One important note, the pin labeling on the schematic follows that of the TUSB2036, as I could not find a way to modify it...Please reference the pinouts in the data sheet for the correct labeling on the TUSB2046. Thank you for all the help!

Just add a powered USB hub. It will probably cost you less than the parts will.

As for the diagram - Build it try it and see.
