Hi, I am a rookie playing with SDR, and I have installed the driver with zadig properly I think, then I try to use rtl_test.exe, the error is like *Found 2 devices:* *0: ezcap usb2.0 DVB-T/DAB/FM dongle* *1:ezcap usb2.0 DVB-T/DAB/FM dongle* *failed to open rtlsdr device #0* Can anyone help? I would really appreciate that Thanks, Benjamin
