Comparing 2 standards across 6 specifications. 6 key differences identified.
Comparing:
Mini-USB
USB-B
Mini-USB (Mini-B) was a compact 5-pin connector common on digital cameras, MP3 players, and the original PlayStation Portable in the mid-2000s. USB-IF deprecated the Mini connector family in May 2007, and Micro-USB replaced it in nearly all subsequent compact-electronics designs.
USB-B (Standard-B) is the squarish connector historically used on printers, scanners, and external hard drives -- the peripheral-side counterpart to USB-A. A 9-pin SuperSpeed variant with a distinctive stacked upper tab was added for USB 3.0, though USB-C has since displaced Standard-B in most new peripheral designs.
