• remove the patch rm ./rtl2832.patch

• config the kernel enter menuconfig and set support for DVB_USB_RTL2832U or edit .config and manually add CONFIG_DVB_USB_RTL2832U

• rebuild the kernel If everything is OK and you get a kernel image , this patch did not break anything! :)

• reboot and plug in your device, you should see something like in dmesg: Rafael Micro r820t successfully identified

• if you build the driver as a module you should load the module: modprobe modprobe dvb_usb_rtl2832u or add it to /etc/modules

This is known to work with some digital radio stick.
