Manufacturer description
The StarTech.com USB3EXT6INBK is a 6-inch USB 3.0 extension adapter cable that solves a specific problem: giving you breathing room around a crowded or hard-to-reach USB-A port. One end is USB-A male, the other USB-A female, and the short 6-inch run adds just enough slack to plug in a wide flash drive without blocking the neighboring port. It supports USB 3.2 Gen1 data transfer rates up to 5Gbps, so a fast thumb drive or external SSD is not bottlenecked by the adapter sitting in front of it. The other use case is port protection. If you are on a bench, in a test lab, or running a retro rig…
