Steps to reproduce the problem:
1. Connect a Novation MIDI device (for example, a Novation Circuit or Launchpad) via USB without installing the novation driver
2. Go to https://pixelpoke.de/midireporter/
3. Install Novation MIDI driver
4. Go to https://pixelpoke.de/midireporter/
5. Compare Values

What is the expected behavior?
I expect the returned values for midiport.manufacturer and midiport.version to somewhat correlate to information provided by Windows itself in the device manager.

What went wrong?
When connecting the synth without an installed driver, WebMIDI API reports "Novation-Focusrite" as the manufacturer and Version 2.0 as the version. The Windows driver manager reports "Microsoft Corporation" and "Version 10.0".

When connecting the synth with an installed driver, WebMIDI API reports "Microsoft Corporation" and Version 10.0 (on Win 10) as the version. The Windows device manager reports "Focusrite A.E." (or something similar) and the correct driver version.

Did this work before? N/A 

Is it a problem with Flash or HTML5? N/A

Does this work in other browsers? N/A 

Chrome version: 52.0.2743.116  Channel: stable
OS Version: OS X 10.11.6
Flash Version: Shockwave Flash 22.0 r0

It seems to me that depending on which driver is used, the Web MIDI API displays different data from different sources. Maybe this is due to the underlying MIDI driver architecture, but I would love to see if this could be improved.

As the standard Windows MIDI drivers are a bit buggy (resulting in data loss when transferring large SysEx packages, for example), we would like to detect if a driver is installed. Given the current situation this is possible but the resulting code would be really confusing.
