Overview

The USB2524-ABZJ is a 4-port USB 2.0 Switching Hub Controller with the ability to electronically reassign and reconfigure any of its 4 downstream ports to either of its two upstream USB ports. This allows two USB hosts to share peripherals and to dynamically reconfigure them. Any configuration of the downstream ports is possible except simultaneous connection to both upstream ports. Up to 8 different configurations can be selected by a dedicated 3-pin interface or the 4-pin interface can be used to directly assign each port to either of the upstream hosts. An external serial EEPROM (or SMBus Host) is used to store the 8 different configuration parameters. However, 8 predefined configurations, as well as generic VID/PID/DID information, are provided as defaults if no external Serial EEPROM is detected at power up. The SMBus interface can be used to configure the hub as well as dynamically re-assigning downstream ports to upstream hosts.
