In this instructable i will explain you how to make your own USB Hub at home. We can never have enough USB ports on our desktops or laptops to fit all of our devices. Even though recent computers comes with a generous amount of ports we still find ourselves wishing for more. There are solutions available, most hubs allow users to connect up to four USB devices.
Check out this homemade USB hub that can connect up to 4 other USB devices, although you had best check that the power supply has enough juice to handle such a huge amount of gadgets attached to it with full protection with the help of fuses.
We just need a generic IC which can support upto 4 devices. I found a cheap USB controller hub IC Genesys 850G which is used in mostly USB hubs even in Belkin 4 port hub also uses the same IC. This IC is easily available on ebay for just 1 dollar.

Step 2: Schematics and Gerbers
I attached the schematics and gerbers for the USB Hub. Print the F_cu file on photo paper and iron it on Copper clad. Solder all the components.
This USB doesn't require any additional software or power. Just attach it with your PC or laptop and your USB Hub is ready.
