Please elaborate "not able". What does not work? What the host sees?

It looks like a single-function USB HID device with multiple top level collections. This should work with Windows 10 or other decent host OS and create a separate HID device for each TLC. Check the report descriptors and the actual data sent for the reports. IIRC you need to use report IDs to distinguish reports sent for different TLCs (the first byte of each report is the report ID).
