PCTVSystems QuatroStick-nano 520e
A combined DVB-C and DVB-T (and Analog TV/radio) USB 2.0 device from PCTVSystems.
Overview/Features
The device also comes with an analog input, but the analog part is not supported by the linux driver yet(?). The analog input provides composite and s-video connectors using an included adapter cable.
See the external product page for more information.
Driver support
Support for the DVB-C and DVB-T part of the tuner has been added to kernel, and include since 3.4 in all stable kernel releases. [1]

Firmware
The DRX-K demodulator requires a firmware file that must be uploaded by the driver: dvb-demod-drxk-pctv.fw
This file can either be downloaded by the get_dvb_firmware script available in kernel source.
Alternatively, you can download the extracted firmware directly from this link
Target directory: /lib/firmware
Frontend
The 520e uses a shared frontend for both DVB-T and DVB-C.
IR Remote Control
The remote control can be used with "inputlirc". During install from lirc, select in the dialog for receiver and transmitter in each case "None". A helpfull side is Configure_VRC-1100_remote_for_Ubuntu. "lirc" alone does not work with this device.
Known issues
In the Windows software "TVCenter" (available from PCTVSystems), there is a option to disable the amplifier. This option is currently not available(?) in the linux driver. This might be the reason why the device has problems locking on some DVB-C frequencies [2].
Latest ACG (Automatic Gain Control) changes in the TDA18271 driver.
If w_scan doesn't find any channels you may want to try a slower timing using "-F -t3" parameters.
