Hi

I've tried to replace .usb_ctrl wth CYPRESS_FX2
But didn't get much futher:

Will I need to do any additional modification - any different firmware
for download ?

Is there any guide how to trace the driver in Windows - does anyone
have any experience to use qemu-kvm for this - will this even work ?

Technilly it looks similar to Leadtek Winfast Gold from this discussion:
http://www.mail-archive.com/linux-dvb@linuxtv.org/msg30055.html

But I'm so far lost how the thing should be initialized.
