A hybrid ATSC USB 2.0 device by KWorld.
Overview
This device is not recognized by version 3.2.0-32-generic (and presumably prior versions) of the Linux kernel.
There is a clip that goes around the coaxial cable connector. The clip can be removed by prying up the ends and sliding it off of the connector. Removing the clip allows the rest of the case to come apart easily and the board to be removed. The following information is provided to aid in the identification of a suitable driver.
The configuration of the KW-UB445-U device appears similar to this device already in the repository:

http://git.linuxtv.org/media_tree.git/blob/HEAD:/drivers/media/video/cx231xx/cx231xx-cards.c
Components Used
- NXP TDA18271HD/C2 (tuner)
- Conexant CX24228-21Z (ATSC 8-VSB and 64/256-QAM Demodulator)
- Conexant CX23102-11Z (A/V decoder & USB interface)
