Alright, so I did locate in pvrusb2-devattr.c the lines:

         { USB_DEVICE(0x0ccd, 0x0039),
           .driver_info = (kernel_ulong_t)&pvr2_device_av400},

... and appended:
         { USB_DEVICE(0x0ccd, 0x10a8),
           .driver_info = (kernel_ulong_t)&pvr2_device_av400},

Where 0x10a8 is my AV 450MX USB device ID. Here is the verdict:

It works. :)

More precisely, I can select the video input between composite (0) and 
s-video (1) (there's only one audio input, so no selection there) and 
mplayer /dev/video1 will play the audio and relevant video, out of the 
box. I haven't played with standards though.

So now the simplest path is probably to slightly modify the name in the 
AV 400 struct to something like "AV 4x0MX" or "AV 400MX/450MX" or...

For info, below is the dmesg. It does complain at first about the device 
appearing to be jammed, then it is as though the device disconnects and 
reconnects, then the driver proceeds ok, except for a warning about 
0x0000 not being a valid video input -- yet mplayer works at once (and 
'0' seems like a valid video input according to v4l2-ctl).

Amicalement,
Albert.
