Virtual Machine setting configuration error

I am using a virtual machine. As I check on the configuration settings of my virtual machine, I usually get this error below:
Failed to access the USB subsystem.
VirtualBox is not currently allowed to access USB devices. You can change this by adding your user to the ‘vboxusers’ group. Please see the user manual for a more detailed explanation.

Do not show this message again
OK
Please help me find out why I get “Failed to access the USB subsystem” errors every time I check my virtual machine settings. Can someone help me fix this issue?
