Ugh, it *does* change on the fly:

And I am guessing your device does not trigger a Unit Attention as a
result. You don't see something like "Inquiry data has changed" or
"Capacity data has changed" in the log, do you?
There does not seem to be a change in capaticy detected - you got a
almost complete section of dmesg from me. Anyway, here's the whole thing
after plugging in:
