# Some PCI devices have the same lspci -mn fingerprint, yet users are identifying them as having different functions. The example below is reported as an ATSC(DVB-T) card by one user and as a DVB-S card by two other users. lspci -vvxxx provides more fingerprint data, and I'm trying to see if there's a definitive way to tell the cards apart from it.
