Device nodes in /dev are created directly by the kernel. If they're missing, that most likely means you don't have the *kernel drivers* (modules) for that type of USB device – e.g. because you're still running kernel 6.12.x so it is trying to load 'USB storage' modules from /lib/modules/6.12.x, but of course you no longer have a /lib/modules/6.12.x as you upgraded the whole package to 6.13.y instead.
For Arch, install the "kernel-modules-hook" package so that it retains a copy of the running kernel's modules even after an upgrade.
