USB Switch Randomly Turns Off

[kromracing]

Hi All,

Four years ago, I started working from home one or two days a week. I have a desktop computer for gaming and my work laptop. I plug both computers directly into my monitor and switch between the two computers' video output using my monitor. For the keyboard and mouse, I have a Starview SV231USB KVM switch. I don't use the video because it's VGA, but I use the USB for the keyboard and mouse.

Everything worked fine until a week ago. I would be gaming and the keyboard/mouse would stop working for a few seconds. I figured the KVM was starting to go, so I ordered a USB switch and hub. I got the same problem with the USB switch and hub! My gaming desktop is running Windows 8.1.

I searched the Intertubes and did the following:

1. In Device Manager, for all the "Generic USB hubs", I went to the "Power Management" tab and unchecked "Allow the computer to turn off this device to save power".

2. In Power Options, under "USB settings", I disabled "USB selective suspend setting".

3. All the motherboard drivers and BIOS were already up-to-date.

I still got the keyboard and mouse randomly cutting out.

Anyone have any other suggestions?

Thanks

Using the same USB ports? Have you tried switching it around just to see what happens?

 

[Burpo]

Have you tried it without the switch?

Hi All. I tried different USB ports and still get the same issue.

If I don't use the USB switch, the keyboard and mouse work just fine. They do not cut out at all. I get the same issue with both the "Starview SV231USB KVM switch" and a brand new "Plugable USB 2.0 Switch".

What motherboard/computer model is this?

Do you have any BLUE SLOT USB on your pc?
If so then you will need to install the USB 3.0 driver up date.(more than likely)

Thanks to everyone who replied and read this thread. I believe the issue is resolved now.

After trying multiple keyboards/mice, multiple USB switches, plugging the keyboard/mouse directly into the computer, buying a separate USB card, and re-installing Windows 8.1, I still ran into this issue.

Over a week ago, I installed a new motherboard. So far, I have not experienced the issue! Looks like the issue is resolved.

Thanks!

Just an update. The issue not resolved. I had the new motherboard for about a week. I only got to do some light gaming, so I didn't get a lot of testing time in. Unfortunately, the keyboard and mouse still randomly stop working. I even tried a new power supply, downgrading from Windows 8.1 to 7, and disabling the onboard sound card. The only way to debug the issue is to keep replacing components, one-by-one. But that will get very expensive.

When I bought the desktop, I was on the fence about desktop vs gaming laptop. I am going to order a gaming laptop and get rid of the desktop. $1200 down the drain!
