I don't have an EZCap. So can't do any tests. Davey reports the EZCap as
giving alsa device ID numbers and strings. But then says he gets 'empty'
streams (0 values) when using these with arecord. Which indicates something
somewhere isn't set up correctly by him. But I can't tell what the problem
may be from here. :-)

If things are not correctly set then it's certainly possible for the
device to initialize OK but to give a completely blank recording...
