Do USB Extenders Really Work And Are They Safe To Use?
Getting a longer USB connection is easy. Getting the connection you actually expected takes a little more care.

USB extenders do work. The less convenient answer is that the term "USB extender" can mean anything from a passive cable to an active repeater or a CAT/fiber extender. They all extend the USB connection, but don't necessarily preserve the same speed, power or features. They're generally safe to use, as long as a unit is properly rated hardware within its stated limits.
This is important when you get past connecting a keyboard and mouse. A 4K webcam, external SSD or USB-C dock can require significantly more bandwidth; a dock can also transmit video and power. An extender can thus "work" while switching to a slower USB mode, disconnecting from time to time or losing a feature you thought you had.
