I've heard back from them. It uses a Cypress CY7C68013A device. Which is
what the PVRUSB2 uses. Problem is that it's essentially an Intel 8051
device that needs some firmware to operate. We'll need that code to see
how the MPEG stream is pulled from the Sky box to push out of the
Cypress USB 2.0 interface.
I've asked Cielplus as well, for whatever code they really do have.
