yes, USB2 is required for all USB-to-VGA adapters that I have ever seen as a
mass product.  The reason is very simple: A full-screen uncompressed video has
much more bandwidth than USB1 can sustain.

I've only ever once seen a pre-mass-production prototype of a USB1-to-VGA
adaptor. And that was in fact an entire PXA27x based linux system with
something like VNC.  Just no configuration or user i/o of any sorts.  But even
that never made it mass-market.
