In some point of discussion She mentioned that mouse worked for a second, then stopped. That's why i told her that it may be worth to ask here. Nevertheless, no chance of help without correct debug info, cause now I'm confused if She is actually stuck on enumerating process, or her mouse isn't accepted by extmou.

so, as freemangordon said, provide dmesg logs that i asked for and please stay with this problem in one thread, unless there will be 100% conclusion that problem belongs to another one.
