请教关于Redhat 9.0 下USB光电3键滚轮鼠标失灵问题

moyage

刚安装的Redhat 9.0, 安装好后在登陆进入系统后短时间内USB光电3键滚轮鼠标(罗技)由正常突然失灵，不能动，重新插拔后暂时恢复正常，但很快由重现失灵,换一ps/2的三键光电出现同样现象,使用mouseconfig尝试过各种配置，但仍不能解决问题，请问是否还需要在其他配置文件里修改？或该如何解决？
谢谢！！

配置情况：
AMD Athlon XP 3000+
KINGMAX 512 DDR400
ATI X9550 (ati-driver-installer-8.26.18-x86.run)
华硕 nForce 4 A8N5X (NFORCE-Linux-x86-1.0-0306-pkg1.run)
希捷 7200 80G+40G
16XDVD
Windows xp sp2 + Red Hat 9.0

这是XF86Config文件的内容:

# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
