Usb Drive Ch341 3 1 Here

This is misleading marketing. The original CH341 chip is USB 2.0 full-speed (max 12 Mbps), not USB 3.1. Sellers often add "3.1" to the listing title for SEO (Search Engine Optimization) because "USB 3.1" is a popular search term. It may also indicate a newer revision of the breakout board (e.g., version 3.1), not the USB standard.
