Maybe a typo when programming the config eeprom. You can rewrite the config eeprom from the adapter with misc/ftdi-eeprom - or with FTDIs own version for Windows from their site www.ftdichip.com. Or is this a twin port device? In this case it may be one of the newer FT2232 chips. We don't have special support for this variant yet, but it would be great if you have one, so I have someone to do tests.

There are additional features in newwer chips, but they have always been backward compatible. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
