A userspace utility prods one of the HID devices and then the top level device exposes an HCI device. Upon S3/resume, a reset-resume happens, and the HCI device is gone. The system thinks that they are in the same state after S3 (with the exception of the missing HCI device) so a UDEV ADD or CHANGE event doesn't happen. -- Mario Limonciello *Dell | Linux Engineering* mario_limonciello@xxxxxxxx
