USB 1.1 vs. USB-C
Comparing 2 standards across 9 specifications. 9 key differences identified.
Comparing:
USB 1.1
USB-C
USB 1.1, released in September 1998, was the first widely adopted USB standard -- 12 Mbit/s Full Speed for most peripherals, with a 1.5 Mbit/s Low Speed mode for mice and keyboards. The original USB 1.0 from January 1996 saw little real-world adoption before 1.1 quickly superseded it.
USB-C is the reversible, oval 24-pin connector now used across USB 2.0 through USB4 and Thunderbolt. It's the only connector required for USB4, and under EU law it became mandatory on most new phones, tablets, and cameras sold in the EU by the end of 2024, with laptops following by April 2026.
