Yes, it seems your configuration is correct.
I have a device here that behaves in a similar way. When I plug it I
get this output:
[12677.625434] usb 2-2: new high-speed USB device number 8 using ehci-pci
[12677.740513] usb 2-2: New device Syntek Semiconductor USB 2.0 Video
Capture Controller @ 480 Mbps (05e1:0408, interface 0, class 0)
[12677.740517] usb 2-2: video interface 0 found
[12678.217418] stk1160: driver ver 0.9.5 successfully loaded
[12678.220618] AC'97 0 access is not valid [0x0], removing mixer.
[12678.220623] stk1160: registers to NTSC like standard
[12678.221681] stk1160 2-2:1.0: V4L2 device registered as video1
Notice the "...removing mixer" line? It's reporting there's no AC97
decoder on the device.
The STK1160 chip has a built-in audio 8-bit ADC block, which is not
yet implemented
by the current driver. If you crack-open your device you should find
it has only two chips:
one should be stk1160, and the other should be saa711x compatible
(such as gm7113).
They are the USB bridge and the video decoder chip, respectively.
Some devices also have a third chip, which should be the AC97 decoder.
Currently, we only support this last family of devices. Namely the
ones with an AC97 decoder chip. The built-in sound ADC is not
supported.
If you want, feel free to check the above on your device. You should
check there's only
two chips and that the kernel says "AC'97 0 access is not valid [0x0],
removing mixer.".
I'll see if I can add support for the built-in sound ADC soon. With
some luck we might
have it this month!
