As the standart kernel already supports video4linux, there's no need to
add it. If you really need to do so, be sure that you also override the
files in "include/" as far as I can see the problem is that you use new
sources but old include files.

New kernels don't need make dep and bzImage. You only have to type
"make" and it builds kernel and modules.

BTW, as I also own such a device and I can't get it running it's vital
for me to hear from your experience. Please come back and tell me if it
worked!
