Subject: [Discuss-gnuradio] RTL-SDR: Failed to open rtlsdr device

Message-ID:

                <address@hidden>

Content-Type: text/plain; charset="iso-8859-1"

 

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.

 

address@hidden rtl-sdr]$ cmake -DCMAKE_INSTALL_PREFIX=/usr -DINSTALL_UDEV_RULES=ON .

 

address@hidden rtl-sdr]$ make

 

address@hidden rtl-sdr]$ sudo make install

 

address@hidden rtl-sdr]$ sudo cp rtl-sdr.rules /etc/udev/rules.d/15-rtl-sdr.rules

 

address@hidden rtl-sdr]$ sudo chown root:root /etc/udev/rules.d/15-rtl-sdr.rules

 

address@hidden rtl-sdr]$ sudo udevadm control --reload-rules

 

But when I run rtl_test I get the following message.

 

address@hidden ~]# 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?
