Using a logitech wireless keyboard and mouse through a unifying receiver (K330 model) with a UGREEN or SABRENT 2 port usb2.0 saring switch on ubuntu 16.04 LTS 64-Bit.
The switch should enable me to press a button and switch the mouse and keyboard from one computer to another without unplugging it (similar to a kvm switch without toggling video as my monitor does that anyway). Up until my latest update this worked fine and works on other Ubuntu 16.04 machines prior to the March 1st update release. Now, I can plug in the receiver to the switch while its set to route to either computer and it works fine, but if I leave the receiver plugged into the switch and activate the change pc button the new pc cannot see the mouse and keyboard (behaves like there is non connected), if I then switch back to the original pc I have the same problem. I have checked this with multiple mice and an entirely new keyboard and mouse section and I achieve the same results.
Tried both switches on another one of our machines that has ubuntu 16.04 and it works fine just like it use to on my machines so I suppose something that was changed in the latest update causes the system to not re-initialize the usb devices when they are plugged into a specific port. I can mitigate the problem by removing the unifying receiver before I switch the pc it is connected to and then plug it back in but this is counter to why I wanted the switch to begin with. Not sure what changed with this latest release but something is causing this to mess up now.
