I was planning to use the USB Scale with Stamps.com in Parallels for Mac. Well the issue at hand here is that for some reason, it doesn't show up at all inside System Profiler, which means that Parallels can't pick it up either. Even Windows-only devices such as an old Windows Mobile phone, and a crappy scanner still picked up in System Profiler and worked in Windows despite not being supported by Mac OS. So why is this scale any different? I even got another one shipped because I thought it was broken!
