I have installed these using the procedures shown in the wiki. I didn’t see 
any errors during the installation. The packages are on the computer but 
they are not listed amongst the sources on GNU Radio Companion.
If I type in the terminal rtl_test –t I get:
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_open error -3
Failed to open rtlsdr device #0

Any suggestions?

Many thanks,
