Then these are integrated like that: RT2831U = USB-interface + RTL2830 DVB-T demod RT2832U = USB-interface + RTL2832 DVB-T demod RT2832P = USB-interface + RTL2832 DVB-T demod + TS interface USB-interface used is pretty same for all these, thus it is split to own driver named dvb_usb_rtl28xxu. SDR functionality is property of RTL2832 demodulator, but I decided to split it to own driver too. Currently that SDR driver has support for devices having following RF tuners: e4000, r820t, fc0012 and fc0013. So if Hans has a device having some of those tuners, it should work. regards Antti -- http://palosaari.fi/
