Debian3.0 and KeyMouse (PS/2) problem

[Jan Krupa <krupa@alpha.sggw.waw.pl>]

My KeyMouse (two buttons and one wheel in the middle ) works
under Win2000 as PS/2 compatible (6 pins) but I cannot force it
to work under Linux Debian3.0 (PC Pentium IV). It does not work 
neither on the console nor under X Window 4. 
On the console gpm does not recognize the mice.
gpm-mouse-test hangs with message: Ambiguous try it again and
tries Baud rate: 1200 then 2400,..,9600 and then starts again 1200,...

Under X Window I tried in XF86Config-4 in Option "Protocol" the following:
"PS/2"  "IMPS/2 "IntelliMouse"   "MouseManPlusPS/2"   "Auto"
None of the Options do not work, I mean that when X Window with e.g. Gnome
is
loaded I can use only keyboard keys and when I move the mouse or click
some button only cursor is "blanking"  but I cannot control the mouse.
When I click the right button the pull down menu appears but I cannot
force the mouse to choose some item from it. I cannot drag window,
put cursor active neither in xterm nor in other window.  

Section "InputDevice"

# Identifier and driver

    Identifier  "Mouse1"
    Driver      "mouse"
    Option "Protocol"   "PS/2"
    Option "Device"      "/dev/mouse"
#    Option               "ClearDTR"


Could someone please help me (suggest how to make the mouse to work under
X Window and on the console).

TIA

Jan
