Direct Answer
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.

A Short-Lived Standard
Mini-USB filled the gap between the full-size USB-A/B connectors and the space constraints of mid-2000s portable electronics, appearing on a wide range of digital cameras, MP3 players, and Sony's original PlayStation Portable. USB-IF formally deprecated the Mini connector family in May 2007, in favor of the mechanically sturdier Micro-USB connector -- a comparatively short official lifespan for a connector that briefly seemed poised to become the universal small-device standard.
Mini-USB hardware still turns up on older surviving devices and some niche equipment, but no current product category uses it as a primary connector.
