USB is 27 years old and 99% of USB devices I've seen used one of just three different ports, two of which are still in wide use. I'd say the fact I can plug a 15 years old harddrive into a brand new PC and it'll just work without any adapter is amazing. Bewildering diversity? Where?
- George83728 3y agoWithin about 5 meters of me I have devices with sockets or cables for USB 2 Type A and Type B, USB 2 Mini (not sure if Type A, B, or AB...), USB 2 Micro (Type AB?), USB 3 Type A, USB 3 Micro (Type B? not sure...) and finally USB 3 Type C. That's seven at least by my count. I probably have some USB 1.1 Type A peripherals in my closet but those might be USB 2, they look the same so I'm not sure. The only devices I counted were: phone, kindle, laptop, PC, mouse/keyboard, printer, portable HDD, and a GPS nav unit. Maybe I'm weird for still using the last one, but otherwise I don't think any of this is particularly unusual.
