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. Thomas -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details. To unsubscribe send a mail to [email protected]
