The old code states addr 08, bit 04 is "battery powered", I am
wondering where that came from...
I have an old email from FTDI support stating this is
the standarized USB configuration descriptor value
from the USB 2.0 spec, section 9.6.3.
-> There's no such thing as the "battery powered" mode.
So I'll just remove the wrong comment.
