What happens if you plug it in after boot?

Same as if I power-cycle the drive (easier than unplugging and
re-plugging the USB cable): it's detected as a USB mass-storage
device, is then scanned for partititions and the device nodes created.

Power cycling of the external drive or the PC?

The external drive

For some reason it seems that when the USB modules are first loaded,
mass storage devices are not properly initialized (my USB mouse, on
the other hand, works just fine)

I've heard of similar problems when using devices connected to a USB hub. If the hub draws power from the USB bus, then some power-hungry devices don't get properly detected at boot time. But if the USB hub has its own power source, things would work better.
