There is quite a lot of communicati= on with the associated USB hub but of course no device communication during resume. Note that there is no device communication during suspend either. T= his is somewhat unexpected to me but perhaps it shouldn't be. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
