One will find that the device actually contains only an USB connector, antenna input, and nothing slot for a smart card . Additionally, a remote control is bundled in the package.
Based upon the analysis of USBsnoop logs, it appears that the control API used for the FX2 chip is the same as that employed by a Conexant reference design, and which is known to be utilised by a few other devices. The control API should be documented on isely.net and as well as inside cxusb.h.
In the bundled Windows driver/software, there are one firmware files, it is dvb-usb-dw3101.fw ,These may or may not have anything to do with this particular device .
