Subdevice labelling question

[sblair]

I would move it to DEVICE_LABEL. There is an expectation that for a given Model ID# for a root or a sub-device that the Device Model Description will always be the same. This would cause problems for you because a controller would fetch the DEVICE_INFO for the subdevices and see they are all the same Model ID# and then only fetch a single Device Model Description assuming them all to be the same.

There is no expectation with Device Label of any two ever being the same.

Thanks Scott

Whould the model ID for each subdevice be the same as for the root device?

Hi again

Ok, I have changed it so the MODEL_DESCRIPTION is not the same for all subdevices and the DEVICE_LABEL differs.

Now, the Enttech USB Pro shows me the same MODEL_DESCRIPTION as expected but it also shows the same DEVICE_LABEL for all as the root.

Now I can't see any difference at all from subdevice to subdevice.

Oh Man!
