hi guys,
i am a linux newbie and i hope you can assist me with my problem. i am trying to test a USB mouse using montavista 2.4.18. i want to trap the packets sent by the mouse device to the host. i have created a program that does a blocking read on /dev/input/mouse0. i discovered that the mouse generates a 3-byte packet. when i researched for a scrolling wheel mouse, i found out that i have to use IMPS/2 protocol and that a 4-byte packet will be generated. when i configured my mouse to use the wheel button, i found out that the Section "Pointer" in /etc/X11/XF86Config uses "IMPS/2" protocol. but when i executed my program, i still got 3 bytes where in fact scrolling is executing well. where did i go wrong? if i understood it correctly, then why can't i get a 4-byte packet from the mouse when i am using the scrolling wheel? is it because of my program? if so, can somebody tell me how to do it rigth? or better yet does anyone know of a utility/tool that traps the mouse packets? any input will be greatly appreciated.
mayet
