可以实现兼容PS/2键盘和USB键盘的Logge 源代码 键盘Logger是Hook 键盘类驱动Kbdclass的分发函数，在类驱动的下面是端口驱动。用DeviceTree 可以看到PS/2键盘的端口驱动是i8042prt,USB键盘的端口驱动是Kbdhid。无论是PS/2 键盘还是USB键盘，在端口驱动处理完IRP之后都会调用上层处理的回调函数，即KbdClass 处理输入数据的函数。-Can realize the compatibility of PS/2 keyboard and USB keyboard Logge source code Logger keyboard Hook keyboard driver Kbdclass distribution function, the drive below port driver. Using DeviceTree you can see the PS/2 keyboard port driver is i8042prt, USB keyboard port driver Kbdhid. Either the PS/2 keyboard USB keyboard, in port driver finished IRP will invoke the callback function, namely the KbdClass processing function of input data.
