Hi,

Bluetooth comm adapters (if that's what this is) were not defined by 
the normal process.  The USB board of directors simply assigned a 
code.  The device class spec isn't available through USB-IF either.

But you can get the list of class codes here:
http://www.usb.org/developers/defined_class

The CDC Ethernet subclass is defined by USB CDC 1.1.  There's some 
clarifying information in the WMC 1.0 spec.  It's possible that 
Broadcom is running Ethernet over the Bluetooth radio, in which case 
the "Ethernet"ness isn't visible from the USB descriptors.

Hope this is helpful.
