README
README.mdHighSpeedUSBHub
I looked at an old USB 2.0 hub I made and though what if I could make a faster one? So I did(whether it works or not is another story). This started right after I discovered the texas instruments site via the guide for making a flight controller by @notaroomba.
This is a USB 3.1 hub which uses a usb 3.1 gen 2 upstream port to 4 usb 3.0 downstream ports via a TUSB8041. Each USB stack (I used x2 stacked usb 3.0 ports as they were more compact, and they reminded me of the raspberry pi 4) is powered by a TPS2051B which is a power switch that has a power limit of around 1A per controller as I recall.
Features
- 4 USB-A 3.0 downstream ports
- 1 USB-C 3.1 gen 2 upstream port
- Powered by the USB-C port (5V 3A)
- Each downstream port is limited to 1A of current and with equal load across each port, 0.5A per port.
- CRYSTAL 24MHz clock for the TUSB8041
Case
Fusion 360 Link here There are two parts of the case:
- The Lid
- The Base The lid has notches which slot into the base to hold it on using the power of friendship and friction.
Getting Started
So ummm, how do I put this...

Firmware
Sooo you won't believe this but it is just a usb hub, it is plug and play

Questions
How big is the HighSpeedUSBHub PCB?
It measures 80.6 × 57 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HighSpeedUSBHub use?
86 parts, built around the SY8089A1AAC, TUSB8041IRGCR, XC6206P332MR and UCM1V151MCL1GS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the HighSpeedUSBHub KiCad files?
From the Acidicts/HighSpeedUSBHub repository on GitHub, at the commit this page was made from: the board is kicad/HighSpeedUSBHub.kicad_pcb and its schematic kicad/HighSpeedUSBHub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HighSpeedUSBHub design in my own project?
Its repository states no licence, so its author keeps all rights: ask Acidicts before reusing the design.
