1.2 General Description
The primary purpose of this board is to demonstrate a full-featured HUB configuration for the SMSC
USB2507 7-port HUB. This does not represent a minimal cost design. The EEPROM allows for
modifications to the base configuration - for example one or more down stream ports can be disabled
or configured as non-removable for compound device application. The DID, PID or DID information
can be changed for the HUB. The top silk screen of the evaluation board is shown in figure 1.
The EVB-USB2507Q board can be configured via EEPROM or from an external SMBus master. If an
external SMBus master is available it can be connected to header J1. Table 1 shows the jumper
settings to select SMBus or EEPROM. Note that internal default is not supported on this board.
The EVB-USB2507Q can configure the hub to report as self-powered or bus-powered. Table 2shows
the jumper selection.
The board itself does not support true bus power mode. The external power supply must be connected
for the board to operate.
A Windows utility E2PROMAPP is included in the package to allow modifications of the base
configuration EEPROM. The bin file evb-usb2507_01.bin contains the base configuration. A screen
shot from the application is shown in figure 2. After changes has been selected click the button "Create
EEPROM File". Note that if the output file name is put file name it the same as the in will be overwritten
with the new values. The output file name can be changed before creating a new bin file. The bin file
format is compatible with most EEPROM programmers.
