This D-Link DUB-C2 cardbus adapter for USB2 but caused so many problems I gave up on it. Hours with D-Link support but card never produced USB2 speeds.I bought an ADS Tech Dual-Link cardbus adapter DLX-181 that arrived today. Nice card: two USB2 ports (one powered via adapter, one unpowered), one firewire 6-pin and one firewire 4-pin ports.Most support and forum gurus say not to install the proprietary drivers but to let W2K with SP4 find and install its own drivers. I did this but to no avail. I suspect all my enhanced USB2 drivers were mucked-up up due to the stupid D-link/OWC drivers.So I installed the drivers that came on the CD (ALi drivers) and card delivers USB2 speeds. 9g of data transfered to my external HD in 20 minutes (vs. 2.5 hours previously). ADS Tech card and drivers are just dandy. USB2 speeds and Firewire when needed.
