Petter Gustad osmocom at gustad.comI keep getting the message "rtlsdr_read_reg failed with -7" whenever I run any of the rtl_ commands. When I run the command after re-plugging the stick it usually works (except the lost samples): rtl_test Found 1 device(s): 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Found Fitipower FC0013 tuner Supported gain values (23): -9.9 -7.3 -6.5 -6.3 -6.0 -5.8 -5.4 5.8 6.1 6.3 6.5 6.7 6.8 7.0 7.1 17.9 18.1 18.2 18.4 18.6 18.8 19.1 19.7 Info: This tool will continuously read from the device, and report if samples get lost. If you observe no further output, everything is fine. Reading samples in async mode... lost at least 84 bytes But if I run any of the rtl_ commands after breaking any previous running command I get: rtl_test Found 1 device(s): 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 Is there a way to completely reset the driver other than re-plugging it? I'm running Gentoo Linux (3.2.1 kernel) Thanks! //Petter
