The device does seem to work, however, no matter what vmux settings are attempted, the result is a green image. Yet, yet it works in Windows.

Here is the em2820 card entry (which should be correct) that is being used:

       [EM2820_BOARD_USBGEAR_VD204] = {
               .name         = "Usbgear VD204v9",
               .vchannels    = 2,
               .norm         = VIDEO_MODE_NTSC,
               .has_tuner    = 0,
               .decoder      = EM28XX_SAA7113,
               .input          = {{
                       .type     = EM28XX_VMUX_COMPOSITE1,
                       .vmux     = 0,
                       .amux     = 1,
               },{
                       .type     = EM28XX_VMUX_SVIDEO,
                       .vmux     = 9,
                       .amux     = 1,
               }},
       },


USB audio is working (with ALSA), but you need to unmute the audio using the next command:

v4lctl setattr mute 0
