A USB standard device descriptor includes iManufacturer and iProduct fields, which are likely the source of the strings displayed above.  I guess the new USB stack doesn't bother to display them.

The 0x0100 is for the mouse; the 0x100e is probably a USB hub, perhaps within the keyboard if the mouse attaches to the keyboard, although the database suggests it was a USB hub within a monitor.

The idea is that autodetection provides a suggested default, at least if it can identify a country for the input devices which are connected to the system.  But users should be able to set up their own language preferences, which might be different from the system default and from other user's settings.

Folks are supposed to use a different product ID for different devices, so you can uniquely identify them.  

I can't promise that every vendor handles this perfectly, any more than folks always ensured that PCI ids uniquely identified a specific hardware version, but one should blame the vendor for being brain-damaged in such cases; it isn't a fault of the USB standard....
