Question USB Switch

Hi Everyone


I hope you’re well and happy.

Does anyone have any experience with using two computer with one keyboard?

We are using a touchscreen connected to a pc works great but we also connect laptops to screens to mirror the display via HDMI. The touchscreen function works on both devices when connecting direct.

I can get any software and im not to sure which device will be correct for this build.

Is there any kind of USB switch (KVM) I could use, that automatically changes between the pc?


Thanks a million for any and all helps

That looks really good and also cost effective but i dont think it would be suitable for this build since it would need to handle different resolutions from the many types of laptops that does be connected and also the button would create to much confusion.

I could say that the screens are already set up its just the USB that i need to somehow split. i was looking a USB Y cable but im not sure if that would actually work

It wouldn't. That's just a 2 port hub with attached cables and the usual Amazon seller behaviour of confusing the issue by adding a lot of other terms to the title.

USB doesn't have any facility for multiple hosts controlling a single client device.

Typically if you want to do that you either disconnect it from one and connect it to another via a physical switch or you get a device that acts as an intermediary and makes the device available through a protocol that does have such support, e.g. a print server to share a USB printer over a network.


When you do you want the automatic switching to happen?

Thanks for the Info, I thought it sounded to good to be true.

The automatic switching is needed when the computer or laptop is turned on like first come first serve, if that makes sense.

My experience is that touch screens do not always work well when you change resolutions. This is down to the touch screen and driver and the way it calibrates to the PC or laptops. This will be your issue, not the switching. You can get software that will do the same thing, but this would need to be loaded onto every machine - which may not work for you.

At the moment we have had about 5 different laptops connected to the screens (1920 x 1080 @ 60hz) with the touchscreen function connected, just a couple windows laptops a surface pro and a 2013 mac book pro, didn’t produce any issues though? Is that what you mean?

I will have to keep a good eye out for it!

Ya unfortunately is software not an option :(

You could talk to a company specialising in KVMs like Aten, they'd likely be able to come up with a solution for you. It's unlikely to be a £10 widget though.

If you are finding the touch screens work fine with a range of laptops, then you can disregard this.

A switch that works on a "first come, first served" basis is likely to struggle. A PC might "Wake" the USB ports without you performing any action - IE an update or someone pressing a key at on the local keyboard.

A manual switch is the usual way of dealing with this and is fairly idiot proof!!
