Applications

The AUA-4000B is a classic early-2000s PCI USB 2.0 host controller card designed for desktops that shipped with only USB 1.1 ports or too few USB ports to meet growing peripheral demands. At the time of its release, USB 2.0 was the new high-speed standard enabling fast external hard drives, CD-RW burners, scanners, digital cameras, and similar devices — a major step up from the 12 Mbps ceiling of USB 1.1. Cards like this were essential upgrades for Windows 98SE/Me/2000/XP-era PCs and are still sought today for retro computing setups, legacy system maintenance, and machines running older operating systems that lack native USB 2.0 support. The AUA-4000B is also compatible with Mac OS X 10.3 and later, making it useful for PowerPC Macs with open PCI slots. Its USB2Connect software simplifies driver installation across the supported OS range.
