Thanks steve, Found it. Its the same files I found at a different place. I don't understand the way to do things. Last time I simply edited the kernel tree and supplied patches to get my changes in. The source for tda18272 is not in the kernel tree I 'git' following the instructions at linuxtv.org. It is in Manu's tree, but the directory structure is slightly different. I don't understand the current development process. Are the instructions at linuxtv.org out of date? In which tree should I edit the following and supply patches against: usb/em28xx/em28xx-cards.c usb/em28xx/em28xx-dvb.c usb/em28xx/em28xx.h On 02/07/2014 12:39 PM, Steven Toth wrote: > On Fri, Feb 7, 2014 at 1:23 PM, The Bit Pit <thebitpit@xxxxxxxxxxxxx> wrote: >> Last May I started writing a driver for a KWorld UB435Q Version 3 >> tuner.
