This card is also known as Azureware AD-CP300.

The development of drivers for this card (and the rest of the Mantis based cards) is pretty much dead and most of the information found on the net is old.

The driver that most information refers to is to be found at http://jusst.de/hg/mantis. But this is a old driver that uses the Multiproto API. Multiproto is not a part of the kernel, more info about it can be found here; http://www.linuxtv.org/wiki/index.php/Multiproto Do NOT use this driver!

There is, however, a newer driver that uses the new S2API (version 5.0 of the LinuxDVB API). It can be found here: http://jusst.de/hg/mantis-v4l

• Download the driver source; http://jusst.de/hg/mantis-v4l/archive/tip.tar.bz2
• Unpack the source and cd into the unpacked directory
• Do 'make menuconfig', navigate through the menus and de-select the 'Philips TDA10023 based' tuner under 'Multimedia devices→DVB/ATSC adapters→Customise DVB Frontends'. Exit and save config.
• Do 'make' and 'make install'
• Finally, load the driver: 'modprobe mantis'

This was tested with kernel 2.6.30.
