Hi André and Marko,
since André did a full quote, I'll take that mail to
answer Marko's part too.

While the EZ-USB series formerly was a product from
Anchor Chips later bought by Cypress, the SL811HS is
a "true" Cypress development. At least I believe so.
To my knowledge the SL811HS has nothing in common
with the EZ-USB architecture. Even I don't know if
the SL811HS has got a builtin µC that can be
programmed freely. Mainly the '811 is an USB host
controller chip that also can be used as an USB
device (client / slave).

Ah yes all the projects there incorporate USB host
applications. As far as I know the Atari people did
already program some 6502 drivers for USB mice and
keyboards.
To make a network alike connection via USB maybe
these "USB network" cables could be used along with
a specialised 6502 driver, don't know?
André, maybe you want to have a talk with Nicolas
Coplin who seems to have done a C64 prototype.

Oh nice, a "sinful web application" (according to a
book I'm currently reading) and a 6502 core for USB,
wow. Unfortunately the datasheet claims that it
would be a keyboard (only ?) controller:
