PCI设备命令

1、lspci

lspci命令用于列出系统中所有的PCI设备，包括设备名称、厂商、型号、总线ID、设备ID等信息，使用方法如下：

lspci

2、lsusb

lsusb命令用于列出系统中所有的USB设备，包括设备ID、厂商、产品名称、供应商等信息，使用方法如下：

lsusb

3、-v选项

使用lspci命令时，可以通过添加-v选项来显示更详细的设备信息，如设备地址、中断号等，使用方法如下：

lspci -v

4、-vv选项

使用lspci命令时，可以通过添加-vv选项来显示更详细的设备信息，如设备类别、驱动程序等，使用方法如下：

lspci -vv

USB设备命令

1、lsusb命令

lsusb命令已经介绍过，可以查看系统中所有的USB设备，使用方法如下：

lsusb

2、-v选项

同样，使用lsusb命令时，可以通过添加-v选项来显示更详细的设备信息，使用方法如下：

lsusb -v

3、-vv选项

使用lsusb命令时，可以通过添加-vv选项来显示更详细的设备信息，使用方法如下：

lsusb -vv

1、如何查看PCI设备的总线和设备ID?

答：可以使用lspci命令的输出结果中的"总线ID"和"设备ID"字段来查看。

$ lspci | grep -i "network controller" | grep -oE "^[0-9a-f]{4}:[0-9a-f]{2}:[0-9a-f]{2}" | tr ":" "
