Unsupported device message, Compliance C.2, part 4

Hi,

We need to comply with the "USB-IF Embedded Host Compliance Plan", section C.2, 
part 4 which states:

"4. Messaging (No Silent Failure):
	a. Unsupported device message. Attach a device that is known not to be 
supported. An appropriate message should be displayed.
	b. If hubs are not supported, a "Hubs not supported" or similar message must 
appear. A generic "device not supported" message is not acceptable on a hub 
connect."


Does anyone have any thoughts on how I would go about this? Has anyone else had 
to deal with this?

I was thinking that it might well be a udev question, but as it's USB 
compliance related I thought I would start on this list.


Aras
