USB_HS库中的错误

使用EF启动器套件（MZ芯片）、MPLABX 4、和声2.04、XC32 1.44加载并测试了CDCL COMPARTPORTH双演示。效果不错。对同一个端口上的回音字符做了一些微小的修改，并从Styth.CONFIG.H文件中定义了一些定义为App.CREAD和测试的。注意：将MHPC/USB选项中的EnpPNT 0缓冲区大小设置为USB Hs的64。将AppRead缓冲区大小从512更改为64。这是用户数组在U***DeVeluxCCDCARD（）函数中的维度。演示不起作用。然后我尝试了不同大小的读写数组（所有都是64的倍数）。只有512个尺寸用于阅读。其他大小的工作为写。这给了我什么，除了头痛几天，所以如果任何人都有奇怪的问题与USB CDC库，检查缓冲区大小，你正在使用的阅读。

    Using EF Starter Kit (MZ chip), MPLABX 4.00, HARMony 2.04, XC32 1.44

Loaded and tested the cdc_com_port_dual demo.  That worked.  
Made a few minor changes to echo characters on the same port and moved some #defines from the system_config.h file to app.c
Reloaded and tested.  Worked again.
Note: The EndPpint 0 Buffer Size in the MHC/USB option must be set to 64 for the USB HS.

Changed APP_READ_BUFFER_SIZE from 512 to 64.  This is the dimension of the user array in the USB_DEVICE_CDC_Read() function.  The demo did not work.

I then tried different sizes for both the READ and WRITE arrays (all with multiples of 64).  Only the 512 size worked for the READ.  Other sizes worked for the WRITE.

This caused me nothing but headaches for days, so if anyone is having strange problems with the USB CDC library, check out the buffer size you are using for the READ.
