在ubuntu 8.10下如何启动dbg_hid调试功能来调试hid.ko和usbhid.ko驱动

《捕获linux内核枚举usb鼠标键盘设备完整log信息》
1.修改Makefile和hid-debug.c
在linux-2.6.27.7/drivers/hid/hid-debug.c中定义如下一行.
static int hid_debug = 1;
同时将文件内的所有EXPORT_SYMBOL_GPL行注释掉
// EXPORT_SYMBOL_GPL
修改linux-2.6.27.7/drivers/hid/Makefile
hid-y        += hid-debug.o

在linux-2.6.27.7/drivers/hid/usbhid/Makefile加入添加../hid-debug.o
usbhid-objs    := hid-core.o hid-quirks.o ../hid-debug.o
或者将hid-debug.c拷贝到usbhid目录,在Makefile中添加
usbhid-objs    := hid-core.o hid-quirks.o hid-debug.o

2.配置设置头文件
/lib/modules/2.6.27-7-generic/build/include/linux/hid-debug.h
添加如下一行
#define CONFIG_HID_DEBUG    1

/lib/modules/2.6.27-7-generic/build/include/linux/hid.h
原来
#ifdef CONFIG_HID_DEBUG
 extern int hid_debug;
#endif

#define dbg_hid(format, arg...) if (hid_debug) \
                printk(KERN_EMERG "%s: " format ,\
                __FILE__ , ## arg)
#define dbg_hid_line(format, arg...) if (hid_debug) \
                printk(format, ## arg)

改为
#define CONFIG_HID_DEBUG    1
#ifdef CONFIG_HID_DEBUG
// extern int hid_debug;
#endif

#define dbg_hid(format, arg...) if (1) \
                printk(KERN_DEBUG "[%04d %s]%s: " format ,\
                __LINE__, __func__, __FILE__ , ## arg)
#define dbg_hid_line(format, arg...) if (1) \
                printk(format, ## arg)

3.可以编译了
