Yes, it helped, I changed Protocol from "MouseManPlusPS/2" to "ImPS/2"
and wheel mouse now works when my Logitech MouseManPlus is plugged in
USB mode + input core driver.
So, I guess it's a very specific bug in the MouseManPlusPS/2 driver ?
A quick look at xc/programs/Xserver/hw/xfree86/input/mouse/mouse.c shows
this driver is the most sophisticated:
With all the special cases, it might be missing the case where the input
core driver is used and mouse is plugged in via USB ?
