I was looking to make a custom USB Hub for a project but I couldnt find any of them that worked and using the chip GL850G. The chip is pretty old and cheap, but in my case I didnt need to use any of the fast transfering USB3, probably the next version can be based on this schematic.
I have took the schematic from a chinese website and re-written on eagle + designed the PCB, which is not the best compact and neat design but it worked as prototype.
I am offering all the files and part lists in case someone will want to make a custom USB Hub.
Enjoy this project?
