Yes.  event13 and event14 are incorrect mappings; as mentioned in the
report, the actual devices are event9 and event10.  The current lsinput
results are:

/dev/input/event9
   bustype : BUS_USB
   vendor  : 0x45e
   product : 0xdb
   version : 273
   name    : "Microsoft Natural® Ergonomic Ke"
   phys    : "usb-0000:00:1a.0-1.2.2/input1"
   uniq    : ""
   bits ev : EV_SYN EV_KEY EV_REL EV_ABS EV_MSC EV_REP

/dev/input/event10
   bustype : BUS_USB
   vendor  : 0x46d
   product : 0xc03e
   version : 272
   name    : "Logitech USB-PS/2 Optical Mouse"
   phys    : "usb-0000:00:1a.0-1.2.3/input0"
   uniq    : ""
   bits ev : EV_SYN EV_KEY EV_REL EV_MSC

(this may not correspond to what was shown in the log at the time since the
USB hub has been unplugged and replugged a few times since then - but they
have consistently had indices 9 and 10 here.)

Yes, that's the correct keyboard model.  The KVM is an off-brand unit that
reports itself as a Cypress TetraHub in lsusb - but that shouldn't be
relevant, the KVM works fine and the mouse and keyboard endpoints are being
correctly exposed.  It's only X that's failing to pick up the devices.

The mouse is, as above, a Logitech optical mouse.

It worked reliably under oneiric.  I'm now running precise, which is where
I've seen the failure.  I have no reason to believe it's tied to kernel
version at all - note that the failure to pick up the devices occurred
during an X session in which the keyboard and mouse previously *had* been
picked up just fine.  And since filing this bug report, a subsequent
unplug/replug has resulted in the keyboard being picked up reliably again,
but the mouse is still not being seen by X (but is being seen by the
kernel).  So it's not even consistent with this version of the X packages.

I've left this X session running for debugging in spite of the inconvenience
of not having my external mouse, because I fully expect that restarting will
cause the bug to be unreproducible again.
