Some days ago I bought a model that identifies with id >> 2040:b131. Does anyone know more about that difference? Is b131 compatible >> to b130? Can the new patches from Matthias Schwarzott be applied here, too? Hi! According to a mail I got some days ago from Ralph Stamm, this is a new hardware revision of the HVR-930C-HD. According to this part of the inf-file: ; Exeter DVB-T/C (Si2158/Si2165) %hcw10bda.DeviceDesc-B131%=POLARIS_XDS_Install.B131, USB\VID_2040&PID_B131&MI_01 the tuner was changed. This revision is using tuner si2158 and demod si2165. The si2165 is supported by my driver (as far as possible currently). For Si2158, see this description http://www.silabs.com/Support%20Documents/TechnicalDocs/Si2158-short.pdf I have not found a driver for this tuner. The challange here is to write a driver for the tuner. >> >> I'm interested in getting my new device supported.

You could try to do the same as I do with the si2165 driver and start by documenting the card in the wiki (a seperate page or just a new section in the existing entry). And then starting with sniffing USB traffic.
