## Long description

The StarTech.com ECUSB3S254F card adapter adds two flush-mount USB 3.2 Gen 1 (USB 3.0) ports to laptops with a 54mm ExpressCard slot. Using a NEC uPD720200 chipset and a low-profile design, the adapter sits flush with the laptop chassis for a permanent, impact-resistant connection while on the move. It supports SuperSpeed transfers up to 5 Gbps and is backward compatible with USB 2.0 and USB 1.x devices.
Advantages
The flush-mount design protects the ExpressCard connection and allows the adapter to remain installed without protruding from the laptop. UASP (USB Attached SCSI Protocol) support provides improved throughput and reduced CPU overhead when used with a UASP-capable enclosure and a compatible operating system. The card is compact, lightweight and uses a proven NEC uPD720200 controller for reliable USB 3.2 Gen 1 performance.
Suitable for
Adding two external USB 3.2 Gen 1 ports to an ExpressCard-enabled laptop
Connecting external drives, flash storage and USB peripherals at SuperSpeed rates
Users who need a low-profile, permanent expansion solution for mobile use

How to use
Insert the ECUSB3S254F into a 54mm ExpressCard slot on the laptop until it sits flush with the chassis. If your operating system supports UASP (for example, Windows 8 and later), connect a UASP-capable external enclosure to achieve higher transfer performance. For standard devices, connect USB peripherals as you would to any USB port; the adapter is backward compatible with USB 2.0 and USB 1.x devices. No external power is required for typical USB devices.
Usage recommendations
For best performance when transferring large files or using SSD-based enclosures, use a UASP-enabled external enclosure and a compatible operating system to take advantage of up to ~70% faster reads and reduced CPU usage observed in testing. Avoid forcing the card in non-ExpressCard slots and remove the adapter carefully if needed to prevent damage to the slot.
