I have installed rtl-sdr driver in my machine. The tarball of the source
I used is attached. The commands I used ( after cd-ying to the source
directory ) are listed.

[[email protected] rtl-sdr]$ cmake -DCMAKE_INSTALL_PREFIX=/usr

[[email protected] rtl-sdr]$ make

[[email protected] rtl-sdr]$ sudo make install

[[email protected] rtl-sdr]$ sudo cp rtl-sdr.rules

[[email protected] rtl-sdr]$ sudo chown root:root

[[email protected] rtl-sdr]$ sudo udevadm control --reload-rules

But when I run rtl_test I get the following message.

[[email protected] ~]# 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

I googled, but not much info is available on this*.* Has anyone come
across such a situation?
