This thread makes a convincing case for why the original USB connector couldn’t be reversible, but there’s a parallel question I’ve never seen addressed: Why couldn’t it have been asymmetrical? The physical design of FireWire was one of its many advantages, in that you could instantly tell, visually and by touch, which side was up by the beveled corners on one side of the plug. I’m guessing the answer here was again cost, that manufacturing an interconnect with two 90-degree angles and four 45-degree angles was more expensive than one with four 90-degree angles, but I’ve never seen any confirmation of this.

> This thread makes a convincing case for why the original USB connector couldn’t be reversible The sole reason as stated by Ajay Bhatt, the project lead at Intel, was cost. They wanted to encourage mass adoption of USB and every cent saved helped in that initiative. The compromise for UX was to make the connector rectangular rather than circular, so that there was a 50% chance of getting it correctly orientated on first try.

FireWire 400 was a great connector! I resisted using FW for the longest time mostly because the cables were more expensive and less common than USB. Once most of my computers had it it started to make more sense for faster file transfers and external drives. They were so much easier to plug in without looking than USB, but the FW800 and mini connector went to a more rectangular shape and somewhat lost that advantage. I never ended up getting a camera or anything else that supported FW, but USB always seemed to work well enough for my (relatively light) use case.
