The "BT5.1 Mouse Mouse" is BT mouse and it can work on Chrome OS.
"BT5.1 Mouse" has customized HID report, I want to communicate with it.
"BT5.1 Mouse Mouse" and "BT5.1 Mouse" are in the same physical device.
It looks like my device was denied by permission broker?
How can I solve this problem? (Attachment contains full system log and device log)
Thanks.

Unfortunately I don't think WebHID can be used with your device since it exposes mouse inputs. Some devices get around this by creating multiple HID interfaces so that sensitive functionality (mouse & keyboard input) is provided by separate interfaces than the vendor's proprietary functionality.
