The FT232AM and FT232BM have product ID 0x6001.
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.

Do you know the chip type inside the adapter?

FTDI devices share the same driver layout.
There are additional features in newwer chips, but they have always
been backward compatible.
