1209 / 2832 - RTL2832U based SDR

There are multiple vendors with different vendor/product IDs, see https://github.com/librtlsdr/librtlsdr/blob/master/rtl-sdr.rules But, because the dongles main purpose is DVB-T, usually the dvb-modules (or original drivers) will lock these devices - unless uninstalling or blacklisting. Registering a new vendor/product ID (not used from original drivers) will allow undisturbed use as SDR device. The USB-dongles vendor and product IDs can be modified utilitzing ‘rtl_eeprom’. Main advantage is to allow usage of 2 devices - with and without modification - in parallel: one for watching DVB-T and the other as SDR.
