Abstract: A USB apparatus (6) having an embedded driver can be operated in any one of the following three modes: a memory operating mode, a wireless communication operating mode, and an interruption mode. The USB apparatus includes a USB interface module (66) for connecting to a USB interface of a host, a wireless communication module (64) for accessing a wireless local area network, a memory module (60) for storing a driver of the wireless communication module, and for reading and writing data, and a switching module (62) for switching the wireless communication module and the memory module. The switching module includes a first analogical switch (622), a second analogical switch (624), and a mechanical switch (620) for controlling switching between the first analogic switch and the second analogic switch. A method for installing a driver of such a USB apparatus is also disclosed.
