dmesg log, S/R, usb_storage device disconnect. dyndbg xhci_hcd, usbcore.

I've posted a dmesg log where the usb_storage device disconnects during resume
and where dynamic_debug for modules xhci_hcd and usbcore are enabled. In the
dmesg log the usbcore messages are not annotated with "usbcore" but as device
related messages "usb 3-4:". There are just few extra messages with usbcore
dynamic_debug enabled. Initially I thought that my misunderstanding was more
profound, but after looking at source I found a few dev_dbg messages from the
usbcore source in the log, for instance "Waited 0ms for CONNECT".
