V=VERBOSE/S: 

May be called from shell/script or Workbench.
The only Argument/Tooltype is V=VERBOSE to get a much lengthier response

Shows the basic information for attached USB Audio devices.
This includes which USB Audio Class the device complies with.

Most USB audio devices are class 1, but some devices are 
class 2, and the two classes are not at all compatible 
with each other.

Most driver packages will only work with Class1 or Class2,
but there's no easy way to tell them apart, This tool
solves that problem.

NOTE: this program will only see unopened USB audio devices.
If it's currently in use, it will not show up in the results.

default will scan for all USB audiostreaming devices, and report
on each:
Interface Number, recording or playback,
Manufacturer Name, if provided
Product Name, if provided
Serial Number, if provided
InterfaceName, if provided
Vendor ID (VID)
Product ID (PID)
USB Class Compliance number

There are typically two audio streaming interfaces per device, 
one playback and one recording.

Here's an example from my Amiga:
***************************************************************

***************************************************************
This represents three Audio devices, each shows as one
"recording" interface and one "playback" interface.
The UMC404HD is class 2, the others are class 1.
The Vendor ID and Product ID of each is also shown.

If you add a VERBOSE argument (or just V from shell/script)
You'll get a fairly complete dump of all the USB descriptors.
That's a lot of geeky information, but might be interesting.

The Verbose output is long.. so redirecting the output
to a text file might be wise. Something like
AudioClassID >ram:MyAudioStuff.txt VERBOSE
will create a file in RAM with all the information.

Source is included. If you find a bug feel free to fix it.
The source is heavy on Printf error checking and also
lots of comments. I'd rather be clear than be cool.

Have Fun
