It looks like the manufacturer of the device you're trying to install didn't release drivers to Windows 10.

As a workaround, we suggest that you contact your manufacturer and ask for the legacy drivers of the device for Windows 7. Once you have the file of the drivers, right-click on it and choose
Extract. Once done, add it as a legacy driver. To do so, see the steps below:

• Go to Device Manager > Action > Add legacy hardware. Follow the virtual steps to add a hardware.
• Once done, it will show you the common hardware types; then, choose IEEE 1394 host controllers.
• After choosing IEEE 1394 host controllers, it will show you the page to select the manufacturer and model of your hardware.
• To choose for the legacy driver you've extracted, click Have Disk >
  Browse. Now it will show you the window to locate the file.

Let us know what happens after doing the suggestions above.
