问题描述： 由于公司规划，后续项目都是使用pm-3,因此有客户提出pm-3的模块在fastboot 下无法识别mirco-usb。
原因分析： 1.通过对比 pm-2 mirco usb ok pm-3 mirco usb fail pm-3 typec usb ok的log发现fail的log没有走“HandlePortPartnerXtach”函数 （BOOT.XF.4.1boot_imagesQcomPkgSocPkgAgattiPkgLibraryUsbConfigLibUsbConfigLib.c）。 初步怀疑是由于typec走的ssusb ,mirco 是high usb导致的

2.这个函数HandlePortPartnerXtach中
if (IS_PORT_UFP(PortMode) ){//&& IS_SDP_CDP(ChargerType)) 条件成立时才会走HandlePortPartnerXtach 1111；失败的log没有走到这里。

所以看下这个CHG_TYPE怎么来的，改了有什么影响？
改了上面的判断逻辑还是不识别：
通过log 发现走的是UsbDevSmImpl.c
继续看下怎么走到这个判断速度的地方的？
失败的时候 DevSmProcessEvent 没走,UsbFnMsg：0一直为0导致没有走进DevSmProcessEvent，那么进而我们看下UsbFnMsg值怎么获取的？

函数本体是 UsbfnEventHandler；它获取的 UsbFnMsg 为0导致mirco 不识别；接着看：
UsbFnMsg = 5 表示 usb attach???
UsbFnMsg没走是因为 UsbDeviceHandleEvent 没走，这个为什么没走？？？
新发现：
mirco -usb 失败的时候 UsbDeviceHandleEvent 就没继续走了

boot_images/QcomPkg/Drivers/UsbDeviceDxe/UsbDeviceDxe.c
在这三个文件中搜 HandleEvent，此时log打印不出来？
解决方案： 那么此时回到起点，最后发现还是因为UsbDeviceHandleEvent这个函数没走，那么回到HandlePortPartnerXtach函数，只有ChargerType这个值有差异: BOOT.XF.4.1boot_imagesQcomPkgSocPkgAgattiPkgLibraryUsbConfigLibUsbConfigLib.c
