When I am connecting my device with laptop. CDC class is getting COM port but my HID(mouse) is not working Although it is showing in Device Manager with Yellow Sign. it means i am doing some thing Wrong here.

I am Sharing few Things.

1: Device Descriptor -->> Please check is it right ?

2: Configuration Descriptor-->> Please check is it right ?

3: Report Descriptor -->> it is correctly working if i am making only Custom Mouse .

    If you don't get help here, you may want to try using the library described at https://community.st.com/s/question/0D50X0000BytFjMSQU/announcement-new-opensource-usb-library-for-stm32f103xx-mcus

    to see if your problem is in the descriptors themselves or in their inclusion in the library (HAL? you didn't say which) you're using. I find it very difficult to implement new USB device classes in HAL, and easy in my library. I'd also be very interested in seeing if it can handle a composite device -- that's on my "TO DO" list at https://github.com/thanks4opensource/papoon_usb#further_development

    Sorry, I can't help with the descriptors themselves -- I find particularly HID descriptors to be absolutely incomprehensible. You may want to compare yours to the ones in https://github.com/thanks4opensource/papoon_usb/blob/master/usb/usb_dev_hid_mouse.cxx

    and https://github.com/thanks4opensource/papoon_usb/blob/master/usb/usb_dev_cdc_acm.cxx which I know work, but again as separate devices, not combined into a composite one.
