Laptop ExpressCard USB 3.0 expansion
This 34mm ExpressCard adapter adds two USB 3.0 ports to laptops or desktops with a 34mm or 54mm ExpressCard slot. It uses a NEC controller chip and maintains backward compatibility with USB 1.1 Full-Speed and USB 2.0 High-Speed devices. The card provides a simple way to upgrade legacy systems with modern SuperSpeed connectivity.
Upgrade from USB 2.0 or missing ports
The adapter replaces slower USB 2.0 connections or fills the gap when a laptop has no spare USB ports. The jump is worth it when transferring large files to external drives or when connecting high-bandwidth peripherals that need USB 3.0 speeds. Buyers who need more than two added ports or an internal header connection should look elsewhere.

Does this adapter fit both 34 mm and 54 mm ExpressCard slots?
Yes, the card is suitable for laptops or desktops with either a 34 mm or 54 mm ExpressCard slot.
What is the correct way to insert the card so the NEC chip initialises properly?
Insert the card fully until it clicks; a partial insert leaves the USB 3.0 ports unpowered.
