Keep in mind that if you don't install the PnP driver, you won't be able to create virtual drives in PnP mode (i.e., those created when the StorageType property is set to STGT_DISK_PNP). If you install drivers in non-PnP mode (this is controlled by the corresponding parameter of the Install method) the warning message will not be shown. Note that the 'Bulk In, Interface' is removed from 'incomplete installation' list and 'Bulk In, Interface(Interface 1)' appears under 'Universal Serial Bus Devices' list.The warning message is shown when the plug-n-play device driver (which is the part of the product driver set) is installed. Once the driver installation is complete, you will see the status change in Device Manager as shown below. Once the installation is complete, you will get a message as shown below. Now go back to Zadig and select 'Bulk-In, Interface (Interface 1)' as shown below. Note that one of the 'Bulk In, Interface' is removed from 'incomplete installation' list and 'Bulk In, Interface(Interface 0)' appears under 'Universal Serial Bus Devices' list. When the installation is complete, you will get a popup as shown below. First, select 'Bulk-In, Interface (Interface 0)' from the driver list dropbox and click button. If you run Zadig, you will get a window as show below. Once you get zadig, driver installation procedure is same as explained in this note. I followed the instruction in the section SDR# (SDRSharp) Set Up Guide (Tested on Windows 10/8/7 32/64 Bit) (XP/Vista Incompatible) of this page and was able to get zadig and install the driver successfully. I didn't haven't zadig by default in the SDR Sharp package. NOTE : I tried this installation again on Feb 2021 with SDR Sharp revision 1788() on Windows 10.

Go to sdrsharp installation folder and run zadig utility as shown below (If you haven't installed sdrsharp, refer to sdrsharp installation page)

If you plug in the device into USB on your PC and Open up Device Manager, you would see following device which is marked as below. Step 1 : Check the status in the Device Manager. In that case, you have to install the device driver seprately as described in this page. But in case of the device that I am using, no software were delivered and I think many of the readers would be in the same situation. In some case, you may get the device driver installation package delivered to you along with the hardware. In this section, I will describe on how to install a driver for the device using RTL2832.
