Subject: Wonky PS2-USB converter issues...

Quite some time ago, I posted about a problematic PS2-USB converter
that I used to connect an old PS2-connector keyboard to my laptop
dock, where the keyboard wouldn't be recognized at boot unless
I unplugged and reconnected it.

Well, I've recently figured out (partly by obtaining a converter
from a different vendor) that the converters both work correctly
when plugged into a USB port that's physically on my Dell Latitude
laptop - but they have issues and require a reconnect cycle when
plugged into the docking station for the laptop. (It took a long time
to figure this out, because *of course* you plug this sort of stuff
into the docking station specifically so you don't have to plug it
in every morning).

So obviously, it isn't the converter that is the problem, but the docking
station is doing "something stupid".  Anybody have suggestions on figuring out
what it's doing wrong?
