OK, second one - no name device is "Realtek RTL2832U reference design"**. First one: Once upon a time there was a "EasyCAP"… "After while crocodile!" …and "EzCAP" was born. http://szforwardvideo.en.alibaba.com/aboutus.html Obviously Easycap EZTV646 != EzCAP EzTV646 http://www.reddit.com/r/RTLSDR/comments/s6ddo/rtlsdr_compatibility_list_v2_work_in_progress/ ezcap EzTV646 0BDA:2838 RTL2832U/FC0012 Some revisions may have the E4000* http://i.imgur.com/mFD1X.jpg (Generic) 0BDa:2838 RTL2832U/E4000* … And, in addition: http://sdr.osmocom.org/trac/wiki/rtl-sdr 0x0bda 0x2832 all of them Generic RTL2832U (e.g. hama nano)** 0x0bda 0x2838 E4000 ezcap USB 2.0 DVB-T/DAB/FM dongle … Maybe? https://sites.google.com/site/myrtlsdr/ "EzCap EZTV646 has got RTL2832U/FC0012. However rtl-sdr must be tweaked to force FC0012 tuner because it has the same PID as EZTV668 (PID: 0x2838) so running it whithout a tweak will select Elonics E4000 tuner. Works, not so good at filtering." … Conclusion: At least two devices share same vid/pid with different tuners - fc0012 vs e4000. How to resolve this from a drivers perspective in a proper way? Beside, there is GPL'ed 'e4k' tuner source code aka 'e4000 improved'*** (Elonics E4000) by Harald Welte http://cgit.osmocom.org/cgit/osmo-sdr/tree/firmware/src/tuner_e4k.c http://sdr.osmocom.org/trac/ http://sdr.osmocom.org/trac/wiki/rtl-sdr http://wiki.spench.net/wiki/RTL2832U*** regards, poma -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
