You're quite right. And now I'm not sure _which_ one it was that
introduced USB support -- Win95/OSR2 or Win98/SE. Whichever it was,
the splash screen announced 'with USB support'.

The OSR2 release for Win95 provided limited USB functionality for a few
devices (HID primarily I believe... mice and a few keyboards). Full USB
support was in Win98. (Or "fool support" if you're a Linux person talking
about Windows...)
