Alone from the pictures of the device they seem to look very similiar 
indeed.

I haven't done it, but I have a first suggestion for you:

In pvrusb2-devattr.c in the array pvr2_device_table you could copy the 
following entry (located at the end of the array):

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

And replace the second value in "USB_DEVICE" with the device ID of your 
AV450 (check with lsusb).

If the two devices are similar technically as well then this should 
already be it. ;)
