DVR using Hauppauge WinTV-DCR-2650 Dual Tuner CableCARD Receiver?

@vonderau_gmail.com, you mentioned at https://docs.google.com/spreadsheets/d/1fHC9QScNUPoEQ6TL5kthK9hYvNUWTM4dhXtdOCYUT6U/edit#gid=1956367671 that it appears to work, but that it needs a manual IP entry. I thought this was a USB device (going by the manual at https://s3.amazonaws.com/hauppauge/manuals/qi_wintvdcr2650.pdf)?

Can you help me understand?

Thanks!
