Interesting. May be worth reverse engineering. Does anybody know if running windows in a virtualbox with USB pass-through allow to sniff the usb traffic? BTW: I didn't know that there was a manufacturer who made Linux support such a prominent feature.

Mine says: [27648.472519] dvb-usb: found a 'Afatech AF9015 DVB-T USB2.0 stick' in cold state, will try to load a firmware [27648.472598] firmware: requesting dvb-usb-af9015.fw [27648.500072] dvb-usb: downloading firmware from file 'dvb-usb-af9015.fw' [27648.567057] dvb-usb: found a 'Afatech AF9015 DVB-T USB2.0 stick' in warm state. [27648.567182] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer. ... I don't know if it is just a question of the firmware, or if different sticks with the AF9015 come with support circuitry that may or may not support PID filtering. @Antti: Do you know?
