- The software computed HID size is not always correct, because the algoritm does not handle unsorted HID descriptors. - Change the way we obtain the report ID. - Use the X/Y/Z+button locations instead for report ID source for ums. - Add more range checks. - Remove Microsoft Mouse quirks. If the positions are moduloed the report length multiplied by 8, the values seem correct. - Some minor style changes. Submitted by: Hans Petter Selasky
