I would personally look into buying a pcie USB card. You can easily passthough PCIe devices with minimal effort and it will work better
Uh probably not that helpful but I am somewhat sure that this was super easy to do from virt-manager (on Arch qemu & kvm, virtualizing Tiny11 )
No, this is not possible. Virt-manager is just a GUI over libvirt. For now libvirt doesn't support USB passthrought by port id, only by device id (which changes on each plug) or vendor id.
Not the person you were replying to, and don't understand exactly what you mean with port and device id. But if it changes every time, -ish, you plug it in, do you mean like /dev/sdX device names? If so, then maybe look at /dev/disk/by-TYPE/ and use those instead? You have stuff there which is the same each time you plug in.
I found this. I didn't look at the code at all but the Readme mentions another project that might help.
this may help, if you're using apparmour.

I could never get that to work for some of my devices,so I had to use virtualbox,which works very well.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
