为什么我的USB设备枚举失败了？

嗨，我是新的USB世界。我最近开始使用MPLAB和声和32位PIC。到现在为止，我试过（使用SUSTCCESS）使用USAT和定时器模块，但现在我尝试在HupPoPH配置器之后制作一个USB HID设备连接。我做了所有的步骤，并将我的固件与例子进行比较，但是我可以。我认为这是一个枚举问题，因为我发现带有枚举状态的图形和PIC检测到电源，并使Deice附接功能，之后（从图形）主机发送重置进入默认状态但不发生，它只接收RESE。这是我正在做的关于“Upj:App.c—UBSyDeice，HythyEdvyRead App.UbBeDeice HiDeVethHANDLE（UBS.DeVice，HythyAdvultiHID，UbjDeVice，HythyEngEvin事件，VUL*EVEDATA，UntPrTrt用户数据）的消息。*与实例示例相同的方式*UBSyDeice、ApviSubBeDeice EvEnthDrand（UbjDeVice事件）、VUT*PATATE、UTIPSTrt上下文）{Unt8}t ActudioEngiguy；UTI1616T FrAMNENUM；UBSySturk附件速度；ASE UBSDEVICE.EngEnviPoByType检测到：sEndEngScript（“UbjDeVice，EnvithPosivEngult\rn”）；AbthDeVelue.UbDeV句柄；StUBE；send_string("USB_DEVICE_EEVENT_EVENT_EVEVENT_SUSPENDED。n")send_ED：send_string("send_send_string("send_USB_DEV_DEV_DEVICE_EEEEEEEEEVENT_EEEEEEEEEEVENT_EVENT_EEEEVENT_SUTETE_SUSPENENENENDEDEDE_USB_UUUSB_DEV_EEVENT_EVENT_SUENENENEN_SUSPENENENDEDE_SUSPDE_SUSPDE。\\\DEVICE_EVENT_RESET.n");break;case USB_DEVICE_EVENT_DEC已确定的：send_string("USB_DEVICE_EEEVENT_EEVENT_DEDEDEDEDEFIFIGURED.\\\\n"")；appData.deviceConConConConfigured=appData.appData.deviceConfigured=false=false;appData.appData.conficonficonficonfi的配的配置=appData=appData.appData.confi配置值=((appData.appData.conficonficonfi配置值==((((((((((((((((((((((((((((((((((((((((((((((((((())USB USB USB USB USB(USB_DEV_DEVICE_EVENT_DADATA_CONFIGURED*)pData)-pData)-gt;配置值;配置值;USB_DEVICE_HID_EventHandHandlerSet;USB_DEVICE_HID_事件处理程序(appData.hid实例appData.hidInsInstanapp，APP_USB设备HIHIDEHIDEDEDEDEDEDEDEHandHandHandHandHandHandHandHandHandHandHandHandHandHand处理程序(uintptptr_t)&appData;activeConConConConConConConConConConConConConConConConConConConConConConConConConConConConConConConConConConConConconfi=((USB_DEV_DEV_DEV_DEV_DEV_ED:send_string("USB_DEVICE_EEEVENT_EEEEEEEEEEVENT_RESRESUM。\\\\\\\\\\n")；break case；断例USB USB USB_DEV UUUSB_DEV_DEV_EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEUUUUUUUUUUUEEEEEEEEEEEEEEEEEEEEEEEdata.u***DevHandle，pData，32；break；大小写USB_DEVICE_EVEN发送_字符串("USB_DEVICE_EVENT_CONVE_CONCON_CONCON_CONTR_trans_trans_TRANSFER_TATATATATATA接收到。\n"")；USB_DEV_DEV_DEV_CONTRTR_TRA_TRATRANSFER_DATA接收到:send_字符串("USB_USB_DEV_DEV_EVE_EVE_CONTR_CONTR_CONTR_CONTR_TRA_TRA_TRA_TRA_TRA_TRA_TRA_DATA_SENT_SENT_DATA SENT_SENT_SENT:中断;案例USB_DEV_DEV_DEV_中断；情况USB_DEVICE_EVEICE_EVENT_EVENT_EVEVE_EEEEEEEEEEEEEEDEDPOINT_ENDPOINT_ENDPOI_ENDPOI_RE_RE_RE_RE_RE_RE_RE_RE_RE_COMPLET:break；断断；案例USB_USB_DEV_DEV_DEVICE_DEVICE_EEEEEEEEEEEEEEEYNC_SYNCH_FRAM_FRAM_SYNC_FRAM:USB_SYNC_SYNC_SYNC_SYNC_FRAM_SYNC_FR_SYYu***DevHandle, &frameNumber,2);break;case USB_DEVICE_EVENT_ERROR:default:break;}//return USB_DEVICE_EVENT_ERROR;}void APP_Tasks(void){.(appData.state){/*应用程序的初始状态。*/case APP_STATE_INIT: {send_string(“APP_STATE_INITrn”)；appData.u***DevHandle=USB_DEVICE_Open(USB_DEVICE_INDEX_0,DRV_IO_INTENT_READWRITE);if(appData.u***DevHandle!USB_DEVICE_HANDLE_INVALID){USB_DEVICE_HANDLE_INVALID){USB_DEVICE_EventHand处理程序集(appData.u***DevHandle，appDataData.u***DevHandHandle，APP_USB设备设备EveEveDeviceEveEveEveEveEveEveEveEveEventHandHandHand处理程序，0)；appData.state=APP_STATE_STATE_WATE_WAIT_WAIT_._FOR_FOR_CONFIFIFIGURATI；send_string("设备层处理程序创建\\\\\\\\APP_STATE_WAIT_._CONFIGUR.：{if(appData.deviceConfigured){/*Device准备好运行主任务*/appData.hidDataRecei.=false；appData.hidDataTransmitted=true；appData.state=APP_STATE_MAIN_TASK;/*放置新的读取请求。*/USB_DEVICE_HID_ReportReceive(USB_DEVICE_HID_INDEX_0, &appData.rxTransferHandle, appData.receiveDataBuffer, 64); }break;}case APP_STATE_MAIN_TASK: {send_string(“APP_STATE_MAIN_TASKrn”)；if(!appData.deviceConfigured){/*Device未配置*/appData.state=APP_STATE_WAIT_._CONFIGUR.;}.if(appData.hidDataRecei.){send_string("Recei.datarn")；if(appData.hidDataTransmitted){send_string("Data..datarn")；appData..DataBuffer[0]=0x81;appData.hidDataTransmitted=false；/*准备USB模块将数据分组发送到主机*/USB_DEVICE_HID_ReportSend(USB_DEVICE_HID_INDEX_0,&appData.txTransferHandle,appData..DataBuffer,64);appData.hidDataRecei.=false;send_string(“Data sendrn”)；/*放置一个新的rEAD请求。*/USB_DEVICE_HID_ReportReceive(USB_DEVICE_HID_INDEX_0,&appData.rxTransferHandle,appData.receiveDataBuffer,64);}break;}break default:break;}}抱歉对于长篇文章，其他函数与示例相同。我正在使用PIC32 MX27 0F256D，使用一个8MHz的晶体，带有PLL的USB时钟。已经检查了USB连接，并在VBUS上安装了一个10uF电容。从USB到PIC：红线VUSB到PIN 42 VBUSWhite线D-到PIN 9 D-Green线D+到PIN 8 D+GND到GND。非常感谢。

    Hi,
I'm new in the USB World. I recently started to work with MPLAB HARMony and 32 bits PIC's. Until now, I tried (sussccefully) use the USART and Timers modules, but now I'm trying to make an USB HID Device Connection following the Harmpony configurator.

I made all the steps, and compare my firmware with the examples but I can't make it, I think that is an enumeration problem because I found the graphic with the enumeration states and the PIC detect the power, and make the DeviceAttach function, after that (from the graphic) the host send a RESET to enter to the Default state but that not happen, it just receive the reset order from the host and after that the PC show a message saying "Undefined device connected".

This is what I'm doing concerning to the USB:

app.c -

USB_DEVICE_HID_ReportReceive (USB_DEVICE_HID_INDEX_0,
&appData.rxTransferHandle, appData.receiveDataBuffer, 64 ); } }
break;}

break;
}}}

Sorry for the long post, the other functions are the same from the examples. I'm working with the PIC32MX270F256D, using a 8MHz crystal, with the PLL for the USB clock. Already check the USB Connections and put a 10uF capacitor on VBUS.

From the USB to the PIC:
Red wire VUSB to PIN 42 VBUS
White Wire D- to PIN 9 D-
Green Wire D+ to PIN 8 D+
GND to GND.

Thank you a lot.
