Finding USB volume names, revisted

[Richard Gaskin]

Two years ago I posted a handler for finding info for removable USB 
drives, based on input from a great many of the regulars here:
<http://lists.runrev.com/pipermail/use-livecode/2010-March/136908.html>

This has worked well for years, but is reportedly failing to find 
removable volumes on Win8 and OS X Mountain Lion.

Anyone here know what needs to be updated for those systems?
