Hi:
There are 4-cdc & 1-hid device(composite device) on my LPC1768 Platform. When power on, usb enum is OK. I can also write data to the CDC Endpoint by calling USB_WriteEP() function and PC can receive the data. But when I write data to the HID IN EndPoint, PC can not read these data. Can any body give me some advice why I cannot write data to HID EP directly? Can only the HID exchange data with PC by HID report?
Thanks a lot.
