That doesn't seem all that significant to me; I guess we have different
measures (to me "significantly slow down the boot process" would be
something on the order of 5-10 seconds or more).
It's over a third of the boot time that Lennart's been discussing.

Well, it seems like 1-2 seconds is a long time just to check, but that
was a rhetorical question.
USB wasn't designed for rapid initialisation and enumeration.
