DISPATCH_LEVEL

)

IOCTL_INTERNAL_USB_SUBMIT_IDLE_NOTIFICATION; the idle machine owns the IRP afterwards.

Records hub over current in the hub hardware key, once per devnode.

First selective suspend of the device; the registry write runs in a work item.

"USB device not recognized" popup for a port.

A hub was attached beyond the allowed tier depth.

The selected configuration draws more power than the port can give.

The controller ran out of bandwidth for the device; fired by the out of bandwidth timer.

Priority 1 to 3, forwarded to the HCD's EvtEndpointSetCharacteristic.

Tells apart devices that claim the same VID, PID and serial number.
