[comp.sys.ibm.pc.hardware] mouse driver init takes a long time

I bought a new mouse: Logitech Mouseman serial.  Very nice, but the
mouse driver (both mouse.com and mouse.sys) takes over a full second
to initialize itself every time a mouse-using program is run.
Interestingly, the Microsoft v 7.00 driver does the same, but the
driver from my old mouse (Philips mouse, driver by Kye) initializes
itself with no perceptible delay.

I've measured this by writing a small program which does nothing but
initialize the mouse and terminate.  It runs to completion in 0.2
seconds using the Kye driver, but 1.6 with the Microsoft and 1.5 with
the Logitech.

The hardware is a 386-33; what can the logitech and microsoft drivers
be doing that takes a full cpu second on a 386-33?
