Hi! Note that this stick is NOT identical to the old Cinergy T Dec 07 16:21:24 tvburk kernel: usb 2-2.3: SerialNumber: CNXT000000000001 Dec 07 16:21:24 tvburk kernel: usb 2-2.3: Manufacturer: Conexant Systems Inc.

Naturally have I tried myself, before asking here. I had to hack dvb drivers in the past, but not as complex as this. The firmware is shipped with the windows software. Neatly hidden inside a Windows installer :) The file there ie merlind.rom, but it is identical to the fw file that linuxtv has v4l-cx231xx-avcore-01.fw I found a driver for 18273 by CrazyCat, but it is for an older version of Linux, so what I have done so far is to take all the files from the TDA18271 driver and renamed them to 18273. I will then use the docs for the two tuners and the code from CrazyCat to make a new driver. I have gotten as far as the driver loading, but I need to figure out whether the tuner is on address C0 (or 60 if you shift out the write bit) or C6. The 18273 address can be selected through a voltage on a pin. So this is how far I have gotten: 2022-12-11T19:06:39.492051+02:00 localhost kernel: [ 1005.466637] cx231xx 6-2:1.1: XX Identified as Terratec TA (card=28) 2022-12-11T19:06:39.492054+02:00 localhost kernel: [ 1005.467195] i2c i2c-11: Added multiplexed i2c bus 13 2022-12-11T19:06:39.492062+02:00 localhost kernel: [ 1005.467235] i2c i2c-11: Added multiplexed i2c bus 14 2022-12-11T19:06:39.620074+02:00 localhost kernel: [ 1005.593790] cx25840 10-0044: cx23102 A/V decoder found @ 0x88 (cx231xx #0-0) 2022-12-11T19:06:41.692044+02:00 localhost kernel: [ 1007.666691] cx25840 10-0044: loaded v4l-cx231xx-avcore-01.fw firmware (16382 bytes) 2022-12-11T19:06:41.736033+02:00 localhost kernel: [ 1007.709539] tea5767: Chip ID is not zero.
