this seems a bug [was express card USB controller]

I need an additional USB controller that can be assigned to a VM different from sys-usb.

Since I have an express card slot, should something like this work?

I bought it and it does not work. Only if I insert it before starting the computer, then I can assign it to a VM with no errors.

But when I start the VM to which it is assigned, it does not start with the error:

libvirtError: End of file while reading data: Input/output error

This is most likely a bug in the Qubes Manager

I got similar problems with other express card USB controllers, so this seems a Qubes bug

I also paste here some lines from Dom0 log, but it does not seem relevant, because the PCI device that I assigned had address 04:00.0, not 00:id.
