USB device disappear after some seccods.

Hello

I am using VMware® Workstation 16 Pro (16.2.5 build-20904516)

After starting a VM all USB devices are visibel.

If I connect a USB device to the VM it disapeers after some secounds.

Also some other USB devices are gone (not connected to the VM).

On the Host the USB device is still visibel as "VMware USB Device"

Why are the USB devices are gone?

PS. Last week everything was OK. Updates?

Some updates.

The USB devices disappear after some minutes, without connecting a USB device.

The same VM (old snapshot) is still working OK. So the problem is inside the VM.

I also reinstall the VMware tools, but there is no change.

If I run 2 VMs (1st with error 2nd OK) on both VM the USB devices disappear. 

So where is the problem?

Is this a bug?
