USB KVM Switch Adapter USB 3.0 Switcher 2 inputs 4 outputs<\/h3>\n\n\n\n

This is a 2 Input 4 Output USB3 switch. With the button on the top the switch toggles a little USB3 switch chip (downsite in the middle) between two host devices (PCs).
The output of the switch chip is then connected to an USB3 hub-chip (bottom site left side) wich connects to the top 4 usb ports.<\/p>\n<\/div><\/div>\n\n\n\n

Because I have on-call duty on many weekends I want to switch my USB devices (mouse, keyboard, microphone, usb-soundcard) via one button press between my home PC and my work PC. But the USB hub is neadly tucked away down behind the PCs. So I have to crawl unter the table and press the button on the hub every time I want to switch PCs (which is multiple times \u00e2 day).

So the idea is to breakout the board and LEDs from this hub to a daughterboard that is mounted within easy reach from my sitting position at my desk.<\/p>\n\n\n\n

<\/div>\n\n\n\n

So lets analyse the hub!<\/h2>\n\n\n\n
