Is it the same ManufacturerID/VendorID as the cinergyT2 device or did you make some adaptations to make your Pinnacle device to work with the cinergyT2 driver?

I hope Tomi will be able to finalize his patch so we will be able to replace the old one.
The old driver is monolithic and does not follow the dvb framework evolutions/bug corrections.
