Heitmueller > http://www.devinheitmueller.com > AIM: devinheitmueller Hmm, not good then :( How we can start that project? I have to tell you that I'm not a programmer and I've added a312 support to cxusb based on the similarities to Avermedia Volar. There is a radio also in that card (I don't know which chipset is responsible for that) + WM8739 for which the driver do exist (wm8739.c). I can try to modify pvrusb2 but the question is if we shouldn't have one "driver" to support both analog and digital TV + Radio on that card?
