Virtualbox kills keyboard when running on Windows 10

[cytam]

OS: Windows 10 build 10240 Virtualbox version: 5.0.4-102546 and 5.0.5-102676

Description:

VirtualBox kills my keyboard every time it is run. Note that this happens when VirtualBox is running for some time, even without starting any VM.

I fresh installed VirtualBox in my new Windows 10 machine (it's a newly built PC with no PS/2 port on the motherboard, so I am using a USB keyboard). Since it's a fresh install the first thing I do is to create a new VM. The keyboard suddenly died out when I attempt to specify where to store the VM files. All LED went off, and pressing the NumLock/CapsLock/ScrollLock keys won't trigger any LED back on. At first I thought it may be the cable of my keyboard got loose. So I checked but found no problem. Unplugging and plugging the keyboard to the same or different USB ports didn't help. Windows even didn't play any sound that indicate a device is being plugged in/unplugged.

I was afraid that it is the motherboard having some issues, but luckily the keyboard came back when I reboot the machine. I tried several times and the result is still the same.

It seems that only the USB keyboard is affected. The mouse still works.

In my experience, keyboard dies after about 1-2 minutes of usage in the stable (5.0.4-102546) build. Using the latest test build (5.0.5-102676). keyboard dies out after about 10 minutes of usage.

I found one similar case in the forum [1]. The op is working on a laptop, while I am working on a desktop.

Not sure if related to the issue, my Windows 10 machine also runs VMWare workstation .

also caps lock continuously flickers between host and guest windows and after 1 hr a hard SHIFTLOCK is enabled so you cant type numbers any more

workaround

shutdown all vms shutdown virtbox

restart virtbox restart all vms
