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
~~~
