Low-profile USB 2.0 expansion card

The StarTech PEXUSB4DP adds four USB 2.0 ports to a desktop, workstation or server through a single PCI Express slot. It fits low-profile and small-form-factor chassis and supplies one internal header for front-bay devices. Each port delivers up to 500 mA from a dedicated power input. Driver support covers Windows 2000 through 7 and Linux with WHQL-certified files.

Builders adding legacy peripherals

The card suits users who need extra USB 2.0 connections for keyboards, mice, printers or older external drives in a compact system. It does not suit builds that require the higher bandwidth of USB 3.0 or later standards. Systems without a free PCI Express slot cannot use this adapter.

Four ports on one PCI Express slot

A single x1, x2, x4, x8 or x16 slot provides three external Type-A ports and one internal Type-A header, all running at the USB 2.0 rate of 480 Mbps. The board is compliant with the PCI Express 1.1 specification and is backward compatible with USB 1.1 devices.

Questions about this item

Will the PEXUSB4DP work in a PCIe x16 slot I already have?

Yes, it is compatible with PCI Express x1, x2, x4, x8, and x16 slots, so it fits the x16 slot you are keeping.

How can I verify the card is running at USB 2.0 speed after installation?

Check Device Manager; the controller should list as a High-Speed USB host and connected devices should show a 480 Mbps transfer rate.

Does the box include a low-profile bracket for my small form factor case?

The card is a low-profile model; the bracket is attached, and a full-height bracket is also supplied for standard cases.
