In the early days of USB, I sat through a presentation from a portable storage vendor at Comdex. They specifically made a point to mention that their external USB storage was seen by the operating system as a SCSI device because SCSI support was widely implemented by all operating systems at the time without having to install additional software. Perhaps ubiquitous OS support was one of the main driving forces behind the SCSI protocol being adopted by so many technologies since.
