USB (ehci) mouse attachment problem

[tlaronde%polynum.com@localhost]

Hello,

This is probably related to PR #44706. But, precisely, in this PR, the
"offending" mouse is a Logitech one, and this also the case here.

But on my NetBSD amd64 6.1.5 system, I have also a Logitech USB 
keyboard, and at least every odd time, if this USB keyboard is connected
directly via USB (and not with a USB/PS2 converter), the logitech
_mouse_ is recognized as a keyboard leading to the lost of the real one.

The kernel is compiled with ehci, uhci and ohci, since some USB ports
are supposed to be for low speed devices (keyboard and mouse) so I
expected the necessity of USB 1.0 support, which seems to request, from
ehci(4), uchi or ohci.

Concerning both keyboard and mouse (both appearing as Logitech keyboard,
the only difference being the second number of the iclass), here is an 
excerpt of dmesg:
