thanks for the patch, applied with minor tweaks to the changelog
and use of spaces instead of tabs.

Regarding the drive levels: What about group 1/2/3?

I don't know the exact details of those chips anymore, but at least
according to libftdi's code there is the same logic for group 1/2/3.

CC:ing Uwe as he contributed the original eeprom decoding
for x232H type chips back in 2010:
commit db099ec562c4e0199c6ec2c71020612e3623f036

    Decode the x232H specific port functions


Cheers,
Thomas
