USB HID Compliance - SMT750C

[kevinwc]

Hello,

I am developing software to communicate with a SMT750C Smart-UPS (firmware ID 1060) using USB HID. Can you confirm that the SMT750C firmware ID 1060 complies with the USB HID details in Application Note 178? The reported usage pages and report IDs from the device do not align with the details in the application note.

Here are the details of the USB HID report descriptor:
