I just ordered a pluggable USB-2.0 sharing (for sharing a single USB device between two PCs) switch from Amazon. Great price (~$13).
Keyboard is Logitech K350, Mouse is Logitech M350.
Both the keyboard and the mouse are wireless and are communicating with the computer via a unifying receiver (USB on the computer side, receiver on desk, (I believe bluetooth between receiver and devices).
I connected the receiver to the pluggable switch (instead of directly to the computer) and the two USB cables which came with the pluggable device into two separate computers.
Result: when switching between the computers by pressing the pluggable little button (aside: I hate this tiny button, should have been larger round, and easier to press) the light turns from green to blue, the second computer gets the keyboard keypresses (as it should) but the mouse doesn’t. IOW: the switch switches the keyboard but fails to switch the mouse.
I tried different ports, both USB2 and USB3, reset the receiver and the keyboard and mouse (disconnect, reconnect, turn on and off). Always the same result: keyboard always works, mouse only works with the original device.
Any idea on how to solve this appreciated. Thanks!
