Gibberish shown when permission denied on opening USB device #106

Currently I get gibberish for SN when trying to start dump1090 when I don't have permissions to read the USB device. I would think the error message should be shown before trying to read the SN, no?

Please fix the device permissions, e.g. by installing the udev rules file rtl-sdr.rules

Yeah, this is a longstanding inherited bug that I never got round to looking at.
