Hi Darren,

Thanks a lot for your detail comments.

One thing I want to address that the difference between standaonle 
widget and called by hob is that the standalone widget add a image 
selection button.
Maybe I use the wrong word "singleton" but that why I update the deploy 
image dialog layout.

Ok, I'll break up it.

Without set the size request, the scroll bar doesn't show the text when 
the deploy dialog shows.
It is ok to a separate patch.

As I mentioned above, I just add a image selection button when the tool 
is run separately. It is convenience So I need to adjust the layout.

This update just to fix runtime error after commit 
094742bed2fc01d55f572da946fcfa7a48521401 when there is no USB device 
then the program crashes.
If we want to deploy to other device, I'll update it.

Fine, if need I would update this part.
