www.usbmadesimple.co.uk/ums_ms_desc_conf.htm You probably have to set bInterfaceProtocol to 0x02 (mouse) in the interface descriptor as well

This should be a 4 byte report. report[0] has the 3 buttons on bit 0,1 and 2, report[1] is x axis, report[2] is y axis and report[3] is wheel data. No report id is set in the report descriptor and then (if I remember correctly) you should not send any report id

Report descriptor mouse setting. I don't know report ID set.

That depends on what mouse descriptor you use. Can you post it here?

If only information about mouse is defined in report descriptor and there is no report id, should I just send 3 or 4 bites of mouse dates ?

It depends on your mouse descriptor how many bytes of data you need to send mouse inputs. A simple mouse is 3-4 bytes + report id.
