无法使用M-Stack获取复合设备进行枚举

我使用的是PICF1825K50，带有M堆栈。我正在尝试创建一个触摸屏设备。它有三个接口。该设备成为USB复合设备。我可以看到配置，看起来是正确的。然而，未显示描述符。一旦我插入它，3个接口中的一个就显示出适当的描述符。现在它们都没有显示出来。我已经看了这些天了，并没有看到任何错误的描述符，这是我认为错误的地方。你们谁能看出我做错了什么？谢谢。

    I'm using a picf1825k50, with m-stack.  I'm trying to create a touch screen device.  It has three interfaces.  The device comes up as USB Composite Device. I can see the configuration, which looks correct.  However the descriptors are not shown.  Once when I plugged it in, one of the 3 interfaces showed the proper descriptor. Now none of them are shown.  I've been looking at these for days, and don't see anything wrong with the Descriptors, which is where I think the error is. Can any of you see what I'm doing wrong?  Thanks.

struct configuration_1_packet {
struct configuration_descriptor config;
struct interface_descriptor interface;
struct hid_descriptor hid;
struct endpoint_descriptor ep;
struct interface_descriptor interface2;
struct hid_descriptor hid2;
struct endpoint_descriptor ep2;
struct endpoint_descriptor ep2_out;
struct interface_descriptor interface3;
struct hid_descriptor hid3;
struct endpoint_descriptor ep3;
};


/* Device Descriptor
*
* Each device has a single device descriptor describing the device. The
* format is described in Chapter 9 of the USB specification from u***.org.
* USB_DEVICE_DESCRIPTOR needs to be defined to the name of this object in
* u***_config.h. For more information, see USB_DEVICE_DESCRIPTOR in u***.h.

我似乎找不到一个“PICF1825K50”设备？“M堆栈”可能是什么？

以上来自于百度翻译

    I can not seem to find a "picf1825k50" device ?
What might a "m-stack" be ?

抱歉意味着它是APIC18F25K50./HTTPS://www. DigiKi.com /Studio DeLiLe/Eng/McCHIP-Tealy/PIC18F25K50-i-SP/PIC18F25K50-i-SP-ND/367150 2M堆栈，是USB库，我使用。

    Sorry meant it's a pic18f25k50.  https://www.digikey.com/product-detail/en/microchip-technology/PIC18F25K50-I-SP/PIC18F25K50-I-SP-ND/3671502
M-Stack is the USB library I'm using.  http://www.signal11.us/oss/m-stack/

我看不到在支持的硬件下提到这个处理器。单元测试示例是否工作？

    I see no mention of this processor under supported hardware.
Does the Unit Test Example work

是的，我有鼠标演示。然后我修改它做触摸屏。实际上，我使用的是PuloLp星板。HTTPS://www-PopuluCOM/Tufft/3156/Realts几乎可以工作。Windows查看设备，并列出3个接口，并有适当的名称。然后，它将删除名称，如果我去属性，它会声明设备没有启动。

    Yes I had the mouse demo working.  Then I modified it for doing a touch screen.  I'm actually using the pololu p-star board. https://www.pololu.com/product/3156/resources  It almost works. Windows see the device, and will list the 3 interfaces, with the proper names.  Then it will remove the names, and if I go to properties, it will state the device did not start.
