Ok here is some more information about the device I got from the
manufacturer...

----------------

The USB firmware is a human interface device class interface. In the
initialization phase of the USB startup it tells the PC it is a HID class
device and that it has 2 endpoint reports. The endpoint zero report
contains a single sensor report and its measured RSSI value. The second
report contains a single measurement and some coefficients needed to scale
the measurement properly.

Report 0

The report zero is 9 bytes long

  Report 1

Report 1 is 24 bytes in length

------------------

It makes no mention that I have to SEND this device any data in order to
receive the data.

When I dump some properties of the device I get this...

Opening HID class device...

Max Lengths:
  Input:   33
  Output:  2
  Feature: 1

So maybe the data I need is just an output report 0 and 1 but since
it doesn't require me to send any data to receive I don't know how to use
"SendMessage" in a way that I would expect output.
