Change device USB properties for DFU Mode

Ah, C:\Windows\inf folder is invisible as the default.

You may need to make it visible.

The second string ''STM Device in DFU Mode'' derives exactly from the INF file, as you expected. But it is copied to the registry at the first plug in. Therefore, to update the message, you have to delete the device instance from the registry once. And re-install the device using modified INF file again.

This utility is convenient to delete (uninstall) device instances from registry, because it lists up all devices registered, regardless of device connection.

Also, the original INF file is renamed and copied to \Windows\inf\ folder, as oemXXX.inf. Delete this oemXXX.inf and oemXXX.pnf files. To find the renamed INF file, search a specific string on the INF file, using ''grep'' utility, or text editor. For example using Windows command line,

> findstr /I vid_0483 c:\Windows\inf\*.inf
