Product information

Description

The StarTech.com ECUSB3S254F 2-Port Flush Mount ExpressCard Adapter adds two USB 3.2 Gen 1 (USB 3.0) ports to laptops with a 54 mm ExpressCard slot, providing SuperSpeed data transfers up to 5 Gbps while remaining backward compatible with USB 2.0 and USB 1.x devices. The adapter is designed to sit flush with the laptop chassis to reduce the risk of impact damage and can stay installed during transport. It incorporates the NEC uPD720200 chipset and supports UASP (USB Attached SCSI Protocol) for improved performance when used with a UASP-capable enclosure and a compatible operating system.

Advantages

The flush-mount design minimizes protrusion from the laptop and protects both the card and the ExpressCard slot. UASP support enables significantly faster transfer speeds and lower CPU utilization compared with conventional USB BOT operation when paired with a compatible enclosure and OS. The adapter offers broad compatibility with older USB standards and small physical dimensions for convenient, long-term installation.

Suitable for

Adding two external SuperSpeed USB 3.2 Gen 1 ports to ExpressCard-enabled laptops
Connecting external storage devices (SSD/HDD) and USB peripherals
Users who need a low-profile, transport-safe USB expansion

How to use

To benefit from UASP performance improvements, use a UASP-enabled enclosure and a compatible operating system (for example, Windows 8 or later) and ensure drivers support UASP.

Usage recommendations

For best performance with storage devices, pair the adapter with a UASP-capable external enclosure and a UASP-supported OS. Keep the card installed during transport to maintain a low-profile configuration, but avoid exposing the exposed edge to direct mechanical impact.
