主机：ubuntu10.04 + vmware
开发板：飞凌OK2440
内核：linux2.6.28.7
交叉编译器：cross-3.4.1
文件系统：开发板自带的yaffs文件系统
bootloader：开发板自带的
问题描述：
移植后，屏幕正常显示到“welcome QtOpia”界面，提示点击鼠标继续，点击鼠标后无反应，移动鼠标，指针也不动，串口间隔打印如下信息：
usb 1-1: new low speed USB device using s3c2410-ohci and address 2
usb 1-1: configuration #1 chosen from 1 choice
input: PixArt USB Optical Mouse as /class/input/input0
generic-usb 0003:093A:2510.0001: input,hidraw0: USB HID v1.11 Mouse [PixArt USB Optical Mouse] on usb-s3c24xx-1/input0
但是使用开发板自带的zImage启动或者自带的已经修改好的内核启动，鼠标可以用。
请各位高手支招，这是什么原因导致的，已经困扰我很长时间了！
串口打印出的启动信息如下：
