USB Passthrough to Containers

[emrainey]

What is the problem you're trying to solve?.
I need to share a USB device connected to my laptop to the software inside the container. There is no native support in Mac for this USB device and the vendor does not support it on Mac either. However, Linux does natively support the device. So I need to run some software in the container which connects to the device in Linux. In my specific case it is a CAN bus device of a particular type which is supported by the Linux kernel in SocketCAN. Mac does not have an equivalent replacement.

Describe the feature you'd like
I would like to be able to setup the device to be shared into the container like docker could do with the -dev flag or something similar with a setting in the finch.yaml to pass the USB IDs in to allow access to one specific device. This would imply that the underlying technology itself on Mac could share the device or make the device exclusively used inside the container.

Additional context
VirtualBox permits such a use by having a filter list based on the USB ID of the device.

I also need this. Unfortunately, UTM's USB passthrough support is currently very buggy and unusable.
