Abstract: The present invention discloses a portable data exchanger with extended USB interface. One portable data exchanger of the present invention can exchange data with another portable data exchanger of the same design connected thereto without using a computer. Further, the portable data exchanger with extended USB interface of the present invention is designed to have the hub-supporting USB OTG capability. Thus, the portable data exchanger with extended USB interface of the present invention not only can function as a slave to be controlled by a standard non-OTG USB host device but also can function as a host to control a standard non-OTG USB peripheral device. To be also compatible with the next generation devices, the present invention also proposes a portable data exchanger with extended USB interface using dual-personality extended USB plug and socket with PCI-express or SATA extensions.

The host interface has a card detecting pin fixed at a level representing that a card is inserted. The removable card interface has an elastic switch connected to the device detecting pin of the controller. The controller detects event and status of a card insertion and removal by a level change of the device detecting pin for setting the event and status in a status register, and informs the host device through the host interface so that the host device reads the status register to determine whether the removable card is inserted or removed.

Abstract: A multi-function electronic card has a host interface, a multi-functional controller and a plurality of function devices.

When a function device issues an interrupt request, an identification number of the function device is stored into the interrupt queue, and only when all the bits in the interrupt status register are zeros, a corresponding bit in the interrupt status register is set as 1 for issuing an interrupt request to the host. When the host has serviced the function device, the interrupt queue is updated and the interrupt status register is cleared.
