Fixed device state not being reset back to the default state if the host sets the address to 0x00.

Fixed Set Configuration requests not being stalled until the host has set the device's address.

Fixed possibility of internal signature retrieval being corrupted if an interrupt occurs during a signature byte read (thanks to Andrei Krainev).
