Still need drivers for the ftdi chip.
All the current usb2serial adaptors do
and AFAIK none of them can act as hosts yet.

Unless you mean go usbweb cam -> pc -> ftdi-adaptor -> s3kit

Could try using one of the older serial webcams.
May be able to find one in a disposal shop or similar.

Have seen an old logitech serial webcam be used
for a similar purpose.

What about the cmucam ?
http://www-2.cs.cmu.edu/~cmucam/cmucam2/
or a cmucam1
Neither are vga, cheapest is around US$100
