Your patch is not based on the current verson of az6027 driver. It currently have
5 devices, and it includes 2 Terratec and 2 Technisat USB ID's:

static struct usb_device_id az6027_usb_table[] = {
        { USB_DEVICE(USB_VID_AZUREWAVE, USB_PID_AZUREWAVE_AZ6027) },
        { USB_DEVICE(USB_VID_TERRATEC,  USB_PID_TERRATEC_DVBS2CI_V1) },
        { USB_DEVICE(USB_VID_TERRATEC,  USB_PID_TERRATEC_DVBS2CI_V2) },
       	{ USB_DEVICE(USB_VID_TECHNISAT, USB_PID_TECHNISAT_USB2_HDCI_V1) },
        { USB_DEVICE(USB_VID_TECHNISAT, USB_PID_TECHNISAT_USB2_HDCI_V2) },
       	{ },
};

The corresponding USB ID's for those devices, according with
drivers/media/dvb/dvb-usb/dvb-usb-ids.h, are:

#define USB_PID_TERRATEC_DVBS2CI_V1			0x10a4
#define USB_PID_TERRATEC_DVBS2CI_V2			0x10ac
#define USB_PID_TECHNISAT_USB2_HDCI_V1			0x0001
#define USB_PID_TECHNISAT_USB2_HDCI_V2			0x0002

Your patch should be adding a new USB ID entry at az6027_usb_table.

Please check if the existing USB ID's correspond to the devices that you're
adding. If not, please rebase your patch against devel/for_v2.6.36 branch of my
git tree, at http://git.linuxtv.org/v4l-dvb.git.

Cheers,
Mauro
