在LINUX环境开发驱动程序，首先要探测到新硬件，接下来就是开发驱动程序。 常用命令整理如下： 用硬件检测程序kuduz探测新硬件：service kudzu start ( or restart) 查看CPU信息：cat /proc/cpuinfo 查看板卡信息：cat /proc/pci 查看PCI信息：lspci (相比cat /proc/pci更直观） 查看内存信息：cat /proc/meminfo 查看USB设备：cat /proc/bus/usb/devices 查看键盘和鼠标:cat /proc/bus/input/devices 查看系统硬盘信息和使用情况：fdisk & disk - l   & df 查看各设备的中断请求(IRQ):cat /proc/interrupts 查看系统体系结构：uname -a dmidecode查看硬件信息，包括bios、cpu、内存等信息

dmesg | more 查看硬件信息
