On June 6, 2014 I purchased 2 USB 2.0 switches - thru Amazon
One is/was used for two computers to a scanner - so far OK
One is/was used for two computers to a color printer - originally worked as expected - now FAILURE!
I have tried all of the " cable switching" possibilities and each will work occasionally, but not regularly or reliability
In every case where I by-pass the USB 2.0 switch and manually connect the printer to each of the computers (one at a time, of course) - the printer will be activated and print
Each computer is equipped with a Plugable USB 3.0 hub - If I connect the printer thru the respective hubs, printing happens. If I connect the switch thru the hubs - nothing happens
Checked device manager - no yellow warning symbols!
I think I have at least one defective USB 2.0 switch - how do I get a replacement
