1.有两个参数不太懂

1. EXT_PORT_NUM = 5
   
2. USB3_PORT_BITMAP = 0x3FE

复制代码

这两个参数应该如何配置呢？

2.老骥伏枥大佬的帖子里的配置参数有这几个

1. [Usb Port 2]
   
2. DEV_BUS = B00:D26:F0
   
3. IN_HUB = 3
   
4. HUB_PORT = 4

复制代码

而我参考了一些其他成功启动的配置文件都没有这两个参数，只有DEV_BUS跟DEV_PORT两个参数。如矿神的配置文件：

1. [Usb Port 1]
   
2. DEV_BUS = B00:D26:F0
   
3. DEV_PORT = 2

复制代码

我看矿神这边贴出来的aida64配置文件也是这种port1下边又有4个port，比如说上图的戴尔鼠标，是在3.0roothub下的port1下的port4口，但是配置文件里边只配置了一个参数“DEV_PORT = 1” 这个参数是怎么来的，为什么是DEV_PORT = 1，这跟老骥伏枥教程里边的配置完全不一样，到底要怎么配置呢？


实际配置的时候无论我如何采用哪种配置方法都无法成功通过u盘引导系统。不知道问题出在哪，希望大佬指点。下面贴上两种配置方法，和我的端口情况：

按照老骥伏枥大佬的教程配置：

1. [Usb Enclosure]
   
2. VENDOR = QNAP
   
3. MODEL = USB
   
4. MAX_PORT_NUM = 2
   
5. USB3_PORT_BITMAP = 0xFE
   
6. EXT_PORT_NUM = 2
   
7. 下边是左上2.0配置

右边的两个口是usb2.0的，左边的口是3.0的，我分别用2.0和3.0设备测试的，所以左边的3.0口有两组数，这边 ...

要是2.0的接口一个就行，3.0的接口除非对应的U盘也是3.0的否则写上也没啥用，调个2.0的试试

右上2.0：1-1.2
应该是IN_HUB = 1
HUB_PORT=1

右边的两个口是usb2.0的，左边的口是3.0的，我分别用2.0和3.0设备测试的，所以左边的3.0口有两组数，这边是作为两个port都写上还是挑一个写上。

右上2.0：1-1.2
应该是IN_HUB = 1
HUB_PORT=1
DEV_PORT=2
右下2.0：3-2
IN_HUB = 3
DEV_PORT_NS=2
可以试试，记不太清了，带NS的应该是3.0接口中负责2.0的部分，要是SS的话就是负责3.0，当然要是接口本身就是2.0，我记得DEV_PORT就可以

这个我特意每个口都插了一遍，口的定位是没有问题

你主板的USB控制器有三个地址，应该有HUB扩展的，要确定你U盘插在哪个控制器负责的端口上，才能正确引导。
