Devices greyed out - qvm-pci gives "failed"

[enmus]

What is the device, and what are the .1 and .2 devices ?

… because of the possible iommu_groups sharing problem, I guess?

Also, I haven’t found all the answers too

Device isn't assignable

What could be the reasons device not used by any qube not to be shown as assignable when running sudo xl pci-assignable-list? The problem is that if I want to assign such a device, I must hide it from dom0, to recreate grub and to reboot. If I want to get it back, the same process, reversed, which is cumbersome. How should I look for the reasons? What is the difference between xen-pciback.hide=(00:xx.x) and rd.qubes.hide_pci=00:xx.x Pointing to documentation to read and learn is preferr…

Assigning device to a qube leads to another device nonassignable

First of all, it is not related to the other issue I have, That device isn’t assignable by itself. Namely, when I assign a device to a qube (HVM, of course), the other device becomes nonassignable, which is checked executing $ sudo xl pci-assignable-list Devices aren’t in the same iommu_group, so that is not the cause. Actually, the device that is assigned (that way causing the other one to become nonassignable) isn’t even found in IOMMU_group, but it works flawlessly in Qubes, assigned or no…
