How to use 2 different drivers for same USB port

[davest]

I am using Windows 7 64 bits and am using a USB dongle which implements a front end for a software defined radio. I have 2 applications and each one uses its own USB driver. Each application works fine as long as it is the only one installed. However, if I install both applications, then Windows will only use the driver of the most recent installation – so as a result, I am unable to use the application which was installed first.
Is there any way to select between the 2 drivers, without having to reinstall the desired one each time I want to use its application?

Maybe an Add-in PCI USB card that uses a different chipset than the one on the motherboard? It would make it easier for identification and you could use the built-in for one software the the Add-in for the other. Some examples:

I've used this one:

I've also use cards with the VIA chipset.

Interesting problem. Not sure how easy a solution but willing to have a look

All Windows drivers are "staged". Meaning they must first be loaded into the DriverStore before they're installed. (Windows only installs drivers from the DriverStore)

Download and run DriverStore Explorer. Click Enumerate. (It only displays the drivers loaded AFTER your Windows install was complete).

Can you see and identify the 2 different drivers in the Store? Are they both in the DriverStore at the same time? You can show me all the information by
> Right clicking -> Select All
> then right click-> Export

You'll either need to zip the csv file it creates or change the extension to txt so you can upload the file as an attachment
