The tarball of the source I used is attached. The commands I used ( after cd-ying to the source directory ) are listed. [manu@iota rtl-sdr]$ cmake -DCMAKE_INSTALL_PREFIX=/usr -DINSTALL_UDEV_RULES=ON . [manu@iota rtl-sdr]$ make [manu@iota rtl-sdr]$ sudo make install [manu@iota rtl-sdr]$ sudo cp rtl-sdr.rules /etc/udev/rules.d/15-rtl-sdr.rules [manu@iota rtl-sdr]$ sudo chown root:root /etc/udev/rules.d/15-rtl-sdr.rules [manu@iota rtl-sdr]$ sudo udevadm control --reload-rules But when I run rtl_test I get the following message. [root@iota ~]# 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 usb_claim_interface error -6 Failed to open rtlsdr device #0. I'm working on Arch linux x86_64, installed from Currnt Release (2013.03.01) I googled, but not much info is available on this*.* Has anyone come across such a situation? -- Manu T S
