On connection of a USB device, the USB 2.0 specification requires
a "debounce interval with a minimum duration of 100ms" to allow the connection to stabilize
(see USB 2.0 chapter 7.1.7.3 for more details).
During the debounce interval, no new connection/disconnection events are registered.

The reset signaling can be generated on any Hub or Host Controller port by request from
the USB System Software. The USB 2.0 specification requires that "the reset signaling must
be driven for a minimum of 10ms" (see USB 2.0 chapter 7.1.7.5 for more details).
After the reset, the hub port will transition to the Enabled state (refer to Section 11.5).
The default value is set to 30 ms to be safe.

After a port stops driving the reset signal, the USB 2.0 specification requires that
the "USB System Software guarantees a minimum of 10 ms for reset recovery" before the
attached device is expected to respond to data transfers (see USB 2.0 chapter 7.1.7.3 for
more details).
