Hello,

I have been attempting to install the RTL-SDR support for Matlab, but I have been running into an issue. I have previously used my RTL-SDR with the SDRSharp software, so I have already setup the driver for it and it works well with that software. I am now trying to get it to work with Matlab but I am running into problems when I attempt the setup of the communication toolbox for RTL. As soon as I start it goes into the part that looks for the driver, it seems to search and then the Zadig software pops up asking me to change the driver. In my case, since I have already setup the RTL, my options do not include the Bulk USB option, and instead it already lists the RTL2838UHIDIR and the driver it has linked to it is already the WinUSB v6.1.7600.16385. At this point I have tried to reinstall this same driver. When I get to the next step to test the connection it always fails, the Radio Name shows the RTL-SDR, but the Radio address and the Tuner show up as Not Found. In the Matlab screen I can see the message "error code -12". I have seen the suggestion to run Zadig as an admin, that did not work. I also tried running Matlab as admin and that didn’t help either. At this point I don’t know what else to try, and I am hoping someone else may have run into this in the past.

Thanks to anyone that can help.Hello,
