Hi,
I want to integrate HID mouse and HID keyboard in a single device. Can you tell me the complete configuration procedure to integrate HID mouse and HID keyboard in a single HID device?
Thanks

Hello,
You will need to combine the hid keyboard and hid mouse example in this case, in specific look at the implementation of hids_init() in terms of updating the report_map and adjusting the number of input reports and report indexes.
This old answer should still be valid for most part, since the report map show how it looks for a combined keyboard+mouse:

Hi Kenneth
Thanks for the reply. I have tested that report map and descriptor, HID connects successfully but does not send any data or show any error.
Here are my report ID, report map, and hids_init().

I recommend to parse the report map from the case I linked and yours here:
http://eleccelerator.com/usbdescreqparser/
Hopefully this should help you find differences between the two, e.g. have you tried using the report map as-is from the case I linked?
Thanks, Kenneth my problem is solved.
