Review on 🔁 Rybozen USB 3.0 Switch Selector - 4 Port KVM Switch Adapter for 2 Computers with One-Button Swapping - USB Peripheral Switcher Box Hub for Mouse, Keyboard, Scanner, Printer PC - Includes 2 Pack USB Cable by Shakim Yates

************************** **** * A NOTICE. You *MUST* need a regular Micro-USB cable to power the Switch. I've been using it for a few days to swap keyboard/mouse between laptop and desktop and it works fine for that purpose. It wasn't a big deal to provide my own power cord as I had many of these, but I wanted others to know about them. I was hoping I wouldn't need it since my devices (keyboard/mouse) aren't considered power hungry. , but until I plugged in the micro USB, the switch box didn't work. The status LED on the console switch was lit, but the keyboard LEDs were blinking and not recognized by either computer. Thought I might have a non-separable one, but after plugging in the micro USB power connector everything worked like a champ.
