USB On-The-Go

Due to its widespread acceptance, USB is becoming the de facto industry standard for connecting peripherals to PCs and laptops. Many of the new peripherals now using USB are also portable devices.

As these portable devices increase in popularity, there is a growing need for them to communicate directly with each other when a PC is not available. The On-The-Go Supplement addresses this need for mobile interconnectivity by allowing a USB peripheral to have the following enhancements:

  • Limited host capability to communicate with selected other USB peripherals
  • A small USB connector to fit the mobile form factor
  • Low power features to preserve battery life

Revision 1.3 of the USB On-The-Go Supplement, the corresponding Adopters Agreement, and other information regarding USB On-The-Go, is available below. Compliance testing for low-speed, full-speed and high-speed USB On-The-Go products is available now.

In addition to passing USB-IF compliance testing and inclusion of its USB On-The-Go products on the Integrators List, companies wishing to use the certified USB On-The-Go logos must have a current USB-IF Trademark License Agreement on file.
