![]() ![]() My suggestion is get things working with just one stick first (if possible) and then worry about adding the second one at a later time. ![]() Have you attempted to just use one RTL stick all by itself to get things operational? SDR# can't access multiple sticks at the same time so in some instances it can be a difficult situation for the application to figure out which stick it should be trying to work with. It might help, it might not, but I recommend people use Windows Update set for "Check for updates but don't install them" so you're notified when something is available but it won't automatically install which could wreck things with the Zadig drivers completely. It sucks that Windows Update tries to push those other drivers on you but the only thing you can do about it is catch that update when it appears (by checking out every update before installation) and hide the update for future purposes, then make sure the Zadig drivers are installed correctly once more - that's IF this is what's happening. I've seen that happen a lot with people using the "cheap USB TV tuners" aka RTL sticks as they're getting started using them with SDR software. If that's the case you have to get rid of that driver too and in the future you have to make sure that update is hidden and avoided for these purposes. ![]() View any installed/connected USB device on your systemĪlso realize that if you have Windows Update set to automatically download and install updates there's a good chance that it's overwriting the Zadig drivers with the one for RTL2832U devices from Windows Update which obviously doesn't work properly for SDR use. ![]() It can be quite a long list depending on your hardware setup but, it does offer the ability to uninstall/totally remove USB drivers if required - some uninstall options don't get rid of them adequately whereas this tool can do it properly. This application (which I use myself from time to time) can show you everything you ever wanted to or didn't want to know about USB devices and drivers in your Windows installation, both used and not used (but there in case a device is used in the future). If absolutely necessary you may have to remove the USB drivers entirely (the Zadig ones) and that can be somewhat tricky to do but it's possible. The Zadig drivers don't require you to have the USB device(s) plugged in to install the drivers - when they're installed (hopefully without issues) and you insert the device they're designed for (based on the hardware IDs) they'll load and the device should become usable. I know you just said you unplugged them but you didn't specify if you plugged them back in before the next attempt to install the drivers. Try installing the drivers without having the RTL stick(s) plugged in when you do so. ![]()
