FX2LP HID kb导致计算机在启动期间卡住

你好：
我们的客户报告了一个与USB相关的问题。
我们的产品使用了CyPress FX2 CY7C68013（USB FIFO）与DSP相结合。我们设计的CyPress FX2 CY7C68013是USB FIFO，支持两个接口，一个是HID键盘，另一个是大容量。
附件是“SLaveSycBixFIFOHEP246KBYV106RAR”是我们的程序。它在Windows上运行良好，但如果我把USB插入计算机，那么我打开电脑。计算机启动过程卡在20～30秒左右（不同的计算机有不同的症状…）请参阅附件：“HIDYKKYDURIGN PCYBOOtiGN STORK.JPG”。
我尝试测试CY3684EZ-USB开发板，安装了HyyKKB示例，它来自CY3684EZEZ-UBSFX2LPYDVK（1）。症状再次出现。我使用USB分析器记录计算机在BIOS中的枚举。我还记录了一个标准的HID键盘。附件“UBS.PACK.RAR”包含两个记录文件。
“标准的KB Windows .USB”是标准的HID键盘。“CyPress HythKB BIOS。USB”是CY3684EZ-USB开发板。
我的USB分析仪是顾问T3。软件是USB协议套件4.60.1406。
我比较了这两种情况，在“CyPress HythKBBIOS。USB”中发现了一种奇怪的情况。请参阅附件“CyPress HythKB BIOS .JPG”。为什么要发出一个HID鼠标报告？我们没有设置HID鼠标。
我检查的问题可以重新出现在主板上：华硕P8Z77 V LK，华硕Z97PRO。
有人遇到过这个问题吗？如何解决呢？请帮帮我。
非常感谢。

  Hi :
     Our customers reported an issue related USB.
Our product used a Cypress FX2 Cy7c68013(USB FIFO) combined with a DSP. We designed the Cypress FX2 Cy7c68013 to be USB FIFO and supported two interfaces that one is HID Keyboard another one is Bulk.
The attachment "slave_syncB_Fifo_ep246_kb_V106.rar" is our program. It is operating fine on windows but if I plug up USB to a computer after then I turn on the computer. It will occur that the computer’s booting process is stuck about 20~30 sec(different computer has different symptom...) please refer attachment: "hid_kb_during_pc_booting_stuck.jpg".
I’ve tried to test a Cy3684 EZ-USB Development Board installed hid_kb example which was from CY3684_EZ-USB_FX2LP_DVK (1.0). The symptom appears again. I used an USB Analyzer to record the enumeration when the computer was in BIOS. I also record a Standard HID Keyboard. The attachment "USB_Package.rar" included two record files.
"Standard_KB_Windows.u***" is standard HID Keyboard’s. "Cypress_HID_KB_Bios.u***" is Cy3684 EZ-USB Development Board’s.
My USB Analyzer is Advisor T3. Software is USB Protocol Suite 4.60.1406.
I compared both, and I found a weird condition in "Cypress_HID_KB_Bios.u***". Please refer the attachment "Cypress_HID_KB_Bios.jpg". Why it send out a HID Mouse report? We didn’t set HID Mouse.
I checked the issue can be reappears on motherboard : ASUS P8Z77-V LK、ASUS Z97-PRO.

Has anyone met this issue? and how the solve it? Please help me.
thank you a lot.
