... LED status options, and non-removable or disabled configuration for each port. The manufacturer, product and serial strings for the hub can be changed in the EEPROM as well. The EVB-USB2524 can also be configured through changing population of resistors to access internal “strapping options”, without using the EEPROM. ...

... Port Assignment The EVB-USB2524 port assignments are selected by four level switches SW1 to SW4 located in the upper right-hand corner. When only one up-stream port, “US 1” or “US 2” is connected to an operational host, all down-stream ports will be assigned to that host. In this case the switches do not have any effect. When both up-stream ports are connected to operational hosts “ ...

... Hardware Configuration The EVB-USB2524 has two sets of resistor jumpers. The first set selects the USB2524 configuration; internal defaults, SMBus slave or EEPROM configuration. The second set enables dual LED mode. 3.1 USB2524 Configuration Selection The USB2524 has three configuration pins CFG_SEL[2:0], that determines the operating mode of the USB2524. The selection of a configuration is done with six resistor combinations shown in Table 3 ...

... LED Configuration The USB2524 supports three different modes for LED indicators: USB, Basic and DUAL LED. The EVB-USB2524 is configured for Basic LED operation, which means that eight LEDs are used to signal port assignment. Each down- stream port has one green and one red LED. When the port is assigned to up-stream port 1 the green LED is lit. ...
