I tried to create composite USB-Device with MSC and HID-Keyboard, but I always get 'ERR_USBD_BAD_EP_DESC' at call USBD_API->hid->init(). MSC is working normal. Also HID Keyboard is working normal if used stand-alone.
So I try to find reason of problem at debug libusbd_177x_8x_lib, but source-code is needed to do.
