Our HID parser has major shortcomings in many ways, which are e.g.=20 responsible for the messed up item positions you are seeing. 2. ums(4) can only handle mice which report relevant events in a report with id 0. If a report with a different id comes in (0x14 in this case), things get messy. I'm currently working on a fix for this as well as our other HID drivers an= d=20 related userland tools.
