I bought a brand new Blackwidow V4 Pro with yellow switches for use in my workplace.
My set up is a main desktop computer and 2 laptops. I am using a powered “Cable Matters” branded switch to go between the 3 computers. The switch has 4 input ports and 4 output but only 3 are in use.
If I select position 1 on the switch for the desktop, all is fine. The rainbow is seen, the keyboard picked up and it works fine.
If I select positions 2 or 3 for the laptops nothing happens. No rainbow is shown and the keyboard is not picked up. If I unplug the USB that runs between the keyboard and the switch and plug it back in for either of these 2 positions, the rainbow is displayed and the keyboard works fine.
A play around with Copilot is suggesting that the board requires more power. but if I plug a cable into the 2nd USB C port, there is no change in behaviour.
What becomes confusing here is that this is my 3rd Blackwidow V4 Pro. The 2 I have had prior to this one were 2nd hand. The first was a green switch but one of the keys worked intermittently, the second was a yellow switch but turned out to be USA specification and also had a faulty key. Here’s the thing, both of those worked fine and were picked up by the respective computer / laptops when the assigned port was selected on the switch.
It is a lot more convenient to use the switch than the the keyboards on the each laptop so I would rather keep the switch.
There is no reason I can see that this one should behave differently. Does anybody have any thoughts on how to resolve this?
