OpenHarmony中由于开源协议的原因，默认使用toybox，而不是busybox。但是OpenHarmony使用的toybox还有一些不完善的地方，比如执行lspci命令无法获取到pci.ids数据库文件，从而无法获取到PCI设备的具体型号，如下图。于是将解决办法分析如下：
/usr/share/misc/pci.ids 是一个数据库文件，它包含了几乎所有已知的PCI设备ID、厂商ID、设备类型和子系统ID的对应名称。
解决办法
1.从https://pci-ids.ucw.cz/处获取到pci.ids数据库文件，编译打包到开发板中，开发板中pci.ids的路径为`/vendor/etc/pci.ids`
2.修改toybox源码，将/usr/share/misc/pci.ids路径改为/vendor/etc/pci.ids

可以获取到pci具体信息，比如笔者板子上有两个rtl8126网卡，一张amd 580显卡
