Some USB devices cannot be used as install media

[Itxaka]

Kairos version:

Master

Under uki some USB devices are not properly detected under initramfs by immucore so they aren't properly mounted under /run/rootfs base which leads to a failure during install as the installer cannot find some expected files.

One the system is booted the devices are available and visible under /dev/disk/by-label with the proper label UKI_ISO_INSTALL so immucore might be missing some required modules

Reported in slack

We requested: Immucore logs ls -l /sys/bus/usb/drivers ls -ltra /dev/disk/by-label dmesg | grep driver

As with our test USB we haven't been able to reproduce it

They seem to be the same modules we already load on immucore....
