Regarding USB (and especially converters from PS/2 to USB):
Sometimes, they are discovered by the kernel _after_ the login
prompt has been displayed, i. e., after booting completed. No
idea why, probably a "slow" firmware inside the converter that
needs some time to load.
Sidenote: I am currently using an IBM model M keyboard with
such an adapter, or to be precise, a chain of adapters (HIL to
DIN, DIN to PS/2, PS/2 to USB), really _sometimes_ the keyboard
isn't present yet when the system displays the XDM login screen;
a few seconds later, it works as expected. And it will continue
working after I have turned to dust many years in the distant
So what you've been observing could be fully normal for your
hardware setting (including the "sometimes" aspect). Also note
that even though USB is a fundamental part of the kernel, the
kernel changes, therefore "detection order" might be affected
after a system (or kernel) upgrade.
