- USB makes it easy to connect all sorts of devices. But when connected devices get their power from different building ground references, as is quite common in industrial environments, the USB cable’s ground wire can create a ground loop path.

The cameras were built in, and although they still did the job, they communicated via RS-485 connections. The hospital didn’t want to tear them out and replace them if it was unnecessary, but it’s getting harder...
