Review on E-SDS 4K HDMI KVM Switch 4 Port USB KVM - Button Switch, Hotkey Switch, Auto Scan Switch, HDMI1.4b & HDCP2.2 Support by Micheal Wolf

I've tried several other USB KVM switches but they all failed to register with the Linux 5.x USB stack. All I got was "Error -11" reading device descriptors. This switch, on the other hand, works perfectly. If you've had trouble with other switches in the past, try this one. That is, instead of emulating ghost devices (USB keyboard, mouse, and monitor), it simulates disconnecting and reconnecting devices to different computers. When switching from my laptop to desktop, the laptop resizes the desktop as if I physically unplugged the HDMI cable, which is a good thing (in my case at least) since all windows are moved to the laptop screen and I always do can still see everything. . USB devices do the same. That being said, the keyboard hotkeys seem to work well with the 3 different keyboards I have (2 mechanical, 1 wireless membrane). Overall I am very impressed and satisfied with this product.
