+EEPROM
+======
+
+the USB2517 USB hub chip gets its configuration from an EEPROM.
+to generate the configuration:
+
+~~~
+ruby eeprom.rb
+~~~
+
+this will create the `eeprom.bin` binary file.
+feel free to adjust the configuration in the generating script.
+
+after having soldered all the parts on the board, connect a programmer (here a MiniPRO TL866xx) on the J4 pin header to write the AT24C02 EEPROM:
+
+~~~
+minipro --device "AT24C02@SOIC8" --write eeprom.bin -s
+~~~
