VirtualBox does not see USB devices in MATE

I switched from LXDE to MATE - but it seems MATE handles USB devices differently. In short under MATE I can no longer get VirtualBox to detect my usb headset to pass through to a host OS (in this case Win10). Dmesg shows that Linux itself obviously detects it:

Code:

In the sound settings for MATE I have tried to toggle both the headset on and off , but virtualbox still no longer sees the headset:

USB device list in VirtualBox:

I use things like discord too, but I did make sure that discord did not use the headset, so I unplugged and plugged the USB headset back in, and when discord saw and asked, I opted discord to not grab the headset for itself, but seems nothing I do gets VirtualBox to see the headset. Nothing else really changed, and yes GuestAdditions for VirtualBox are installed. Yes I have checked the button in the USB list, and it still does not detect anything, and this is not under --Current but in 14.2.

Also I noticed that even my keyboard and mouse aren't listed, unlike in LXDE - so again I suspect MATE handles USB differently. Not like I actually want to pass my keyboard and mouse, just my headset - but I can't.

The way I understand VirtualBox USB filters it is a way to automatically connect a particular USB device to a guest. Otherwise you need to manually connect it via the Devices pull down menu. Is the headset listed in the guest's devices -> USB menu? Once it is connected to the Guest, the device is disconnected from the host.

Hmm, I expect/assume that USB devices are desktop independent regardless of OS.

Probably has something to do with VBox settings for this particular VM and maybe missing VBox extras.

In LXDE it would show it, if I went in the USB devices in VirtualBox and clicked on the + icon to show the devices to add to the list, but again under MATE , nothing not even my keyboard and mouse. All I know is it worked in LXDE, I mean yea if push comes to shove I'll just go back to LXDE - but I kinda want to know why MATE is not allowed VirtualBox to even detect any of the USB devices, and I am wondering if Plasma5 (when Slackware 15 is out), will exhibit similar behavior like MATE, who knows.

No, the extras or in this case Guest additions are installed - otherwise I wouldn't actually be able to boot Windows - VirtualBox would throw errors - So I honestly have no idea, other than again to conclude that MATE is somehow preventing VirtualBox perhaps, I don't know. Again the only thing changed was me installing MATE.

Have you got the Extension Pack installed?

I have yes - which I would like to correct myself from my earlier post; because without the extension pack itself, I wouldn't be able to boot a guest OS - VirtualBox would throw errors - however it will boot the guest OS with or without GuestAdditions - which again I do have also installed on the guest OS too.

Must be a quirk of Mate. :)

Ok, I get it now you clicked on the add button but it only shows an empty square.

Is your user a member of the vboxusers group?

Thats it! I don't know how or why that got removed. *facepalm* :foot: Checked /etc/groups and added myself and now boom:

Turns out the quirk was the user, experiencing the dreaded ID10T error :redface:

No vaccine for PEBCAK. Unfortunately.
