We have a terminal server that several end-users log into, and each user has a USB shipping scale DYMO Pelouze S250 attached to their machine. The shipping program is ShipRush.
Unfortunately (or fortunately for your company, I guess), RDP does not support passing this USB shipping scale through the RDP session.
Thus, we have installed your excellent software, and it works flawlessly. It has been very easy to setup and use.
