How can I get Virtualbox USB support work on Impish?

I've tried a lot of stuff to get USB support work on a Ubuntu Impish host system, however, with no success at all.

As recommended here on this site, I tried to to replace the distribution's version with Oracle Virtualbox OSE, however, Impish does not seem to be supported by Oracle yet. The package manager complains there is no release file available. http://download.virtualbox.org/virtualbox/debian/dists/ doesn't list an impish folder.

webmaster@dev:~$ sudo lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 21.10
Release:    21.10
Codename:   impish

I've installed the distribution packages:

root@dev:/home/webmaster# aptitude search virtualbox~i
i   virtualbox                      - Virtualisierungslösung für x86-Rechner - g
i A virtualbox-dkms                 - x86-Virtualisierungslösung - Quelldateien 
i   virtualbox-ext-pack             - zusätzliche Funktionen für VirtualBox, Dow
i   virtualbox-guest-additions-iso  - ISO-Abbild mit den Gasterweiterungen für V
i A virtualbox-qt                   - Virtualisierungslösung für x86-Rechner – G

Actually my unprivileged user starting the guest system is in the vboxusers group

root@dev:/home/webmaster# groups webmaster
webmaster : webmaster adm cdrom sudo audio dip plugdev lpadmin sambashare vboxusers

From my user having the vboxusers group there is no USB device shown.

webmaster@dev:~$ vboxmanage list usbhost
Host USB Devices:

<none>

As superuser vboxmanage recognizes my USB devices, also the device in question Lovense USB dongle ID 1915:520a, however, it is busy. No special software on the host is using this device but a bluetooth manager seems to auto-activate this bluetooth dongle even when I disable bluetooth and replug the dongle.

I even tried a catch-all-USB-filter in the VM, but no devices are found.

Questions:
How can I get USB support work on my host system?
How can I tell Ubuntu to let my Lovense bluetooth dongle untouched by the host system?
I've read somewhere, this could be a license problem and Oracle's OSE could fix the issue.
Can I install VirtualBox OSE for another compatible distribution on Ubuntu Impish? Which one?


Actually, for some reason the distibution's version of the VirtualBox extension package does not seem to support the USB functionality. As I have read somewhere else, there might be license issues.

The reinstall of the extension package from https://www.virtualbox.org/wiki/Download_Old_Builds fixed the problem. (currently version 6.1.26) The system will ask you to open the download with VirtualBox, which will start an upgrade process automatically.
