Product Overview
Used IOI U3H414B 4-port USB 3.0 hub board with upstream cable and power leads
Condition
Used, removed from working demanufactured equipment with cosmetic signs of handling only. It is not new stock and it is not factory sealed. More than one of these is in stock, so the photographs show a representative unit rather than the specific board reserved for you: on the unit photographed, the component side is silkscreened U3H414B, Rev. 1.1, PCB-00505-01, and a white factory label near the board edge reads 10611018-1 / 44U3H414B2 / BOM V1.1.1. All four downstream USB-A shells are bright and square with their blue inserts intact, the upstream USB-B shell is clean, and the green two-position screw terminal at J2 is already fitted with a twisted red and black lead pair whose free ends are stripped bare. Electrolytics stand straight, the RoHS lead-free mark is clear, and no burn marks, bent shells, or missing parts are visible. No bench test result is recorded for these boards, so treat the photos as the condition guide. It is supplied in a clear anti-static bag alongside a coiled blue USB 3.0 A-to-B cable.

Product Overview
The IOI U3H414B is a board-level industrial USB hub that breaks one upstream USB-B host connection out to four downstream USB 3.0 ports rated for 5 Gbps SuperSpeed, with backward compatibility for USB 2.0 and USB 1.1 devices. It is built in a 3.5-inch bay / FDD footprint for direct chassis mounting, and it needs an external 5 V DC supply through the green screw terminal for stable operation under load rather than borrowing power from the host. The downstream ports are individually silkscreened USB1 through USB4, the main hub silicon carries a Texas Instruments marking beginning TUSB80, and the power section runs through an LM1084 regulator and a shielded inductor marked 100, all legible in the close-up photos. IOI hardware turns up in installations that ask for steady throughput and predictable port behavior over long duty cycles, which is exactly the job a bare board like this is bought for.
Key Features

- One upstream USB-B host interface
- Backward compatible with USB 2.0 and USB 1.1 devices
- 3.5-inch FDD form factor for chassis mounting
- External 5 V DC input through a green two-position screw terminal at J2
- Downstream ports silkscreened USB1, USB2, USB3 and USB4
- Board marked U3H414B Rev. 1.1 and PCB-00505-01, label 10611018-1 / 44U3H414B2 / BOM V1.1.1
- Green LED indicators in a black block housing at the board edge
- Plated mounting holes through the board for standoff or chassis mounting
- RoHS lead-free marking on the component side
- Includes a coiled blue USB 3.0 A-to-B cable and a fitted red and black power lead pair
Applications
- Machine vision integrator adding four camera ports inside a sealed control cabinet where a consumer hub has no place
- Data acquisition engineer who needs the logger, the DAQ box and two dongles on one powered upstream link
- NVR or kiosk builder routing fixed USB peripherals to a front bay instead of leaving cables hanging off a motherboard header
- Bench technician who wants a powered board-level hub bolted to a test fixture rather than sliding around the bench
Frequently Asked Questions
Does this hub need its own power supply?
Yes. The listing specifies an external 5 V DC input for stable operation under load, and the board takes it at the green two-position screw terminal silkscreened J2. The red and black lead pair is already fitted to that terminal with the free ends stripped bare, so you land them on your own 5 V rail. No power supply is included.
What exactly comes with the board?
Three things, all visible in the first photo: the hub board, a coiled blue USB 3.0 A-to-B upstream cable, and the two-wire red and black power lead already screwed into the terminal. There is no bracket, faceplate, mounting hardware, driver disc or power brick in the photos, so do not plan on any.
Will it drop into a 3.5-inch bay?
The board is described as a 3.5-inch bay / FDD form factor and it carries plated mounting holes for standoffs, but it ships as a bare board with no bracket. Measure your bay and hole pattern against the photos before you commit, since chassis vary more than the nominal size suggests.
Which board revision will I receive?
The unit photographed is marked U3H414B, Rev. 1.1, PCB-00505-01, with the factory label 10611018-1 / 44U3H414B2 / BOM V1.1.1. More than one unit is in stock, and we cannot promise the board we pull for you carries that same revision or label. If your build depends on matching a specific one, message us before you order and we will read the markings on the unit going in your box.
It is a used pull, so what am I actually taking on?
You are getting a used pull from working demanufactured equipment, cosmetically handled, with no bench test result recorded on our side. That means the photographs are your condition guide, and you should plan to power it up on your own 5 V supply and confirm all four ports before it goes into anything that matters. What you are not taking on is guesswork about the condition grade or what ships in the box, and it comes with our no-hassle satisfaction guarantee. Shipping is $8 flat rate and free once your order passes $28, and orders leave the Idaho warehouse the same or next business day.
Somebody's machine gave this board up long before its solder ever looked tired, and it still has four SuperSpeed ports and no faceplate to hide behind. Land 5 V on the screw terminal, bolt it into your own cabinet, and put it back to work moving data.
