18 TODO:
19 - Merge Uwe's eeprom tool. Current features:
20 - Init eeprom defaults based upon eeprom type
21 - Read -> Already there
22 - Write -> Already there
23 - Erase -> Already there
24 - Decode on stdout
25 - Ability to find device by PID/VID, product name or serial
26
27 TODO nice-to-have:
28 - Out-of-the-box compatibility with FTDI's eeprom tool configuration files
