How can I attach a USB stick to my Win10 vm?

I am unable to attach a USB stick either from command line (using vboxmange) or creating a filter in GUI.

After following "USB basics and troubleshooting" I am still unable to create a filter or otherwise attach a USB drive.

Here is the Minimal Information Needed:
-Virtualbox 6.04, extensions and Guest Additions for 6.04 installed
-Host: Ubuntu64 18.04 (actually, Pop-os64 18.04)
-Guest Win10Pro64
-VM log attached

Additional information:

ID:
uid=1000(bob) gid=1000(bob) groups=1000(bob),4(adm),27(sudo),125(vboxusers)

VBoxManage list usbhost:
Host USB Devices:

<none>

notes:
1) I get the same result whether I have VM running or not
2) If I try to attach usb I get:

vboxmanage controlvm "Win10Pro64 "  usbattach ca6cc119-223c-4868-89fd-27220d8c0043 

VBoxManage: error: Machine 'Win10Pro64 ' is not currently running

3) If I try to attach with VM runnning,I get:

vboxmanage controlvm "Win10Pro64 "  usbattach ca6cc119-223c-4868-89fd-27220d8c0043
VBoxManage: error: The USB device with UUID {ca6cc119-223c-4868-89fd-27220d8c0043} is not currently attached to the host

4) The error above (numbered 3) above occurs whether or not USB is attached to host.

Why not simply access the drive as a shared folder? Why mess with the complexities of having a VM use a physical USB device?

I tried using it as a shared folder as well and was likewise unable to do so.

There are other USB devices that I think cannot be shared as folders as they are not folders.

If the intention is to no longer support USB in Virtualbox, than this would be a potential solution.

Does the 'groups' commands also list the vboxusers group membership of your current user?

My answer addressed the implied question asked, not "other USB devices". Obviously my question has a very easy answer if USB is truly required: but that does not seem to be your scenario.

I think so. It includes me (the one and only user) and vboxuser (as well as adm and sudo).

Is that what you mean?

I think I have found the problem:

The cli command:
VBoxManage list usbhost

Results in: "None"

However:
sudo VBoxManage list usbhost

Results in list of all (several) USB devices.

I tried to run sudo VBoxmanage startvm [vm] but the VMs were not available to user "root". After playing around a bit, I found that although I was in vboxusers group, the VM did NOT have permissions for vboxusers. I am not sure how this changed.

Resolution:
Changed permissions on VM to "groups" "vboxusers". This appears to be the solution; ability to capture USB restored (file sharing problem also incidentally resolved).
