(TL;DR: use Lunatone's DALI Cockpit SW to talk to your python-dali using
an emulated protocol.)
My USB-to-DALI interface is connected to a tiny headless Pi Zero, which
is running some Python code (built on top of python-dali) for stuff like
circadian color temperature control, automatic blinds, automatic light
based on movement, etc. This all works well, but every now and then I
have a need to run Lunatone's DALI Cockpit to perform some changes in my
devices' configuration.
That's a Windows application, so I would usually fire up a VM with
Windows and the DALI Cockpit, stop my automation, and then use usb-ip to
export the USB device over network from my embedded server, e.g.:
 ssh root@private.example.org systemctl restart usbip-bind@17b5\:0020.service
...then import that at my desktop, e.g.:
 usbip attach -r private.example.org -b $(usbip list -p -r private.example.org | grep 17b5:0020 | cut '-d:' -f1 | awk '{print 1ドル}')
...and finally attach that to the VM:
 echo "<hostdev mode='subsystem' type='usb' managed='yes'><source><vendor id='0x17b5'/><product id='0x0020'/></source><address type='usb' bus='0' port='3'/></hostdev>" | virsh attach-device win10 /dev/stdin
That works, but it's a pain, and the automatic lights at the WC won't
react to movement, and it's not great if it's dark in there.
So I got fed up and wrote this tiny emulator of the Lunatone DALI-2 IoT
Gateway. The idea is that you can run this on the Linux machine which
has the USB-to-DALI interface already connected, and you can let your
Windows VM connect to that over IP, using the device's emulated
Websocket entry point. It's possible to run this either as a standalone
application, or you can simply put it into your application code.
