d-link dsb-500 2-port usb 1.1 pci adapter

From the ManufacturerThe D-Link DSB-500 is a 2-port Universal Serial Bus USB PCI controller. It allows connection of up to 2 USB peripherals, devices, or USB hubs to a Windows 95 OSR2 or Windows 98 PC. The DSB-500 is targeted at users with older PCs that have no integrated USB support, and users with newer PCs who wish to add additional USB ports. The DSB-500 provides two type 'A' downstream ports for connecting USB peripherals and USB hubs. Its 32-bit PCI architecture is compliant with PCI version 2.1. As a standard USB host controller, it directly interfaces between the USB bus and the operating system.

The DSB-500 operates as the root USB hub to provide two downstream interfaces. It will accept USB data from any attached peripherals, hubs, or other devices in compliance with USB Specification version 1.1. Supporting both low-speed 1.5M bps devices and high-speed 12 Mbps devices, each port of the DSB-500 creates a bridge between the attached USB peripheral or USB hub and the host computer. The DSB-500 provides up to 500mA of current to any attached USB peripheral, device or USB Hub. This function allows any bus-powered devices to operate without the need of an external power adapter.

The DSB-500 is packaged with all necessary manuals and is a true plug and play device to ensure an easy and quick installation.
