Product: 4 Port Powered USB Hub - USED Open Box Description: Note: This product is USED and comes AS-IS in an open box! FINAL SALE - No Refund - No Return - No Credit - No Exchange Universal Serial Bus (USB) port technology has emerged in response to the proliferation of external peripheral devices (scanners, digital cameras, removable drives, etc.), that are increasingly being connected to the latest generation of computers. The USB behaves in a similar fashion to conventional bus ports (i.e., serial, parallel, PS/2), but since it does not require any IRQs, more devices can be attached to the system, and the problem of IRQ conflict is eliminated. Since many older computers don?t have USB connectors on board and most new computers come with only one or two USB ports, USB hubs have been developed to provide a means to connect up all the USB peripherals that users may want to use. The UH-9124 is a four port USB hub that serves as a cable concentrator and bridge between the computer?s USB Host Controller, and USB peripheral devices attached to the system. The UH-9124 provides four Downstream ports for USB devices to plug into, with LED indicators to display information about power status and overcurrent detection for each port. It supports both full speed (12 Mbps) and low speed (1.5 Mbps) devices, such as keyboards, mice, joysticks, etc., and can be daisy chained to provide as many ports as the user requires.
