help
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).
The device may ignore any data transfers during the recovery interval.
The default value is set to 30 ms to be safe.
