Hi Rolf,
I do not have a USB network card around to try the same over here but I've asked a few friends if they could. While not able to recreate let me ask a few things to get this started ...

1. you mention that "given an IP by the host" which clearly indicates it isn't fully passed through (or failing at doing so and given back). You posted the guest dmesg afaics, it might be useful to look at what the host think is right/wrong while you try to do this.
Could you try to gather `sudo dmesg -w`, `sudo journalctl -f` and `sudo tail -f /var/log/libvirt/qemu/<guestname>.log` from when you try to attach it?

2. How do you issue and configure the attach command?
Do you use virt-manager or an XML + virsh or anything else?
If so how is your guest config as well as the one for the device to pass look like?
