Re: RTL-SDR No reception

rtlsdr dongles have two bulk in interfaces. Alas on windows only one can be used at a time. They are the usual TV tuner and its IR controls, respectively. You want the first one, bulk in interface 0. I have a Terratec dongle (0CCD 00D7) with the "Bulk-In, Interface (Interface 0)" and "Bulk-In, Interface (Interface 1)" designations for the tuner and IR respectively. It only shows up once in RTLTool and the good thing is that it works fine. So I am trying to guess why RTLTool might object. It appears the dongle has the right ID information. I presume you have had it turned off at least once before you tried to read the dongle if you renamed it.
Note that you cannot run RTLTool while something like SDRSharp may have the dongle opened. The lack of strings down in the dongle renaming area suggests it could not read the information from the dongle or it could not open the dongle.
Pull the dongle, reinsert it, and check again with device manager and to make sure it comes up as 0bda 2838. Then with nothing else running try the RTLTool.
I wonder if some security tool is blocking access to the dongle.
I reopened the RTLTool project and made one change that "might" help diagnose the problem. But, really, the only problem that should prevent it from opening fully is an inability to open the dongle at all.
