The exact name on the device is "WinTV-Nova-S2" and is not listed on the LinuxTV Hauppauge Wiki. It was bought back in December so is "New".
Windows automatically downloaded the Hauppauge driver describing it also as a PCTV 461e. The NextPVR server recognises it as a "PCTV 292 e/461e BDA 28179 TV Tuner S"
I dont want to abandon my LibreElec server for a a Windows server just to be able to use this USB DVB-S2 tuner. I will contact Hauppauge Support to see what they say.
If you read the b-rad issues on GitHub (best place for Hauppauge Linux support) you will see that Hauppauge marke the Pinnacle 461 (as shown on your Windows BDA driver) branded as a Nova S2 type 3 which isn't supported in Linux.
