How do I distinguish between nearly identical usb devices, when iSerial not available for type usb

Hi,

I am trying to attach a usb device, but I have multiple devices with same vendorid and productid. How can I distinguish between them, so I don’t attach them all.

So I think there are a couple of things we can do here:

Add a serial field to the resources API and allow passing that to usb type devices for selection
Also allow setting bus and device as alternative to vendorid/productid. The downside to those is that they can kinda change under you.

Could you file both of those separately at Issues · lxc/incus · GitHub?

When attaching usb devices, to a instance with vendorid and productid, all matching devices is attached to the instance. If the device type usb, had a serial number option, it would be possible to distinguish between devices with identical vendorid and productid. # Steps to reproduce 1. Plug multiple usb devices, with same vendorid and productid into host 2. Attach devices to a instance, with device type usb 3. Enter the instance 4. List devices in /dev/bus/usb/... 5. Compare with host devices, to see multiple devices has been attached to instance
