The present disclosure relates to a system and method for enabling implementation of a secondary function of a universal serial bus (USB) device on a computer that the USB device is communicating with, wherein an operating system of the computer does not have a required driver which needs to be mapped to the USB device to enable implementation of the secondary function. The system involves a USB device which has the required driver for implementing the secondary function stored therein. The required driver can be supplied to the computer from the USB device using a control which selects the secondary function of the USB device.

An information processing apparatus includes: an operating unit capable of recognizing a peripheral apparatus. The operating unit includes: a first recognizing unit configured to recognize, when a peripheral apparatus is connected to the operating unit and identification information about the connected peripheral apparatus is included in peripheral apparatus information including predetermined identification information, the connected peripheral apparatus as a first peripheral apparatus; and a second recognizing unit configured to recognize, when a peripheral apparatus is connected to the operating unit and the identification information about the connected peripheral apparatus is not included in the peripheral apparatus information, the connected peripheral apparatus as a second peripheral apparatus.

[Problem] To enable a user to control a virtualization system without wasting resources. [Solution] A virtualization system containing an operation unit, an operation reporting unit, a message processing unit, and an operation processing unit. The operation unit outputs a signal on the basis of a user operation. The operation reporting unit transmits to a network an operation message generated by appending, to first operation information indicating the content of the operation corresponding to that signal, a header addressed to a server providing virtual machines. The message processing unit generates second operation information indicating that the operation indicated with the first operation information has been performed with respect to the virtual machine corresponding to the transmission source of that operation message. On the basis of the second operation information, the operation processing unit instructs the virtual machine corresponding to the transmission source to perform the action corresponding to that operation.

An apparatus includes a pass-through module that includes connector pins to connect with at least one active portion of a motherboard connector and to separately connect with at least one inactive portion of the motherboard connector. A routing function on the pass-through module redirects a set of bidirectional lanes from the connector pins connected to the active portion of the motherboard connector to the connector pins connected to the inactive portion of the motherboard connector to enable a connection of the set of bidirectional lanes to at least one other motherboard resource connected to the inactive portion of the motherboard connector.

A device includes an interface configured to connect to a communication link. A controller of the device is configured to generate a redundancy code using first data and second data, and to transmit the redundancy code together with the first data to the interface.

Example implementations relate to chipset reconfiguration based on device detection. For example, a method includes detecting, by a computing system, that a storage device is connected to an input/output (I/O) interface of the computing system, and reconfiguring a chipset of the computing system based on the detected storage device. The method also includes performing a power cycle on chipset standby power to trigger a chipset configuration reload.

Disclosed is a mobile device which comprises a CPU, a USB Type-C interface and a switching circuit. The switching circuit is configured to switch a connection line of two preset pins of the USB Type-C interface to connect UART TxD and UART RxD pins of the CPU, upon detecting that a UART cable is inserted into the USB Type-C interface.

A method is provided in one example embodiment and includes receiving by a network element a request from a network device connected to the network element to update a shared resource maintained by the network element; subsequent to the receipt, identifying a Base Address Register Resource Table (“BRT”) element assigned to a Peripheral Component Interconnect (“PCI”) adapter of the network element associated with the network device, wherein the BRT points to the shared resource; changing an attribute of the identified BRT from read-only to read/write to enable the identified BRT to be written by the network device; and notifying the network device that the attribute of the identified BRT has been changed, thereby enabling the network device to update the shared resource via a Base Address Register (“BAR”) comprising the identified BRT.

A motherboard module having switchable PCI-E lanes includes a CPU, a first PCI-E slot, a second PCI-E slot, a first switch, and a second switch. 1st to a-th processor pin sets of the CPU are switchably electrically connected to 1st to a-th first PCI-E pin sets of the first PCI-E slot or (2N−a+1)th to 2N-th second PCI-E pin sets of the second PCI-E slot via the first switch to form PCI-E lanes whose number is a. (a+1)-th to 2N-th processor pin sets of the CPU are connected to the second input terminal of the second switch, and the second output terminal of the second switch is switchably electrically connected to (a+1)-th to 2N-th first PCI-E pin sets of the first PCI-E slot or 1st to (2N−a)th second PCI-E pin sets of the second PCI-E slot to form PCI-E lanes whose number is 2N−a, wherein 1<a<2N.

In some embodiments, a system is provided for communicating USB information via an extension medium. The system comprises an upstream facing port device (UFP device) and a downstream facing port device (DFP device). The UFP device and the DFP device are communicatively coupled via a non-USB extension medium, and allow a host device communicatively coupled to the UFP device and a USB device communicatively coupled to the DFP device to communicate via USB-compliant techniques. In some embodiments, the DFP device generates synthetic request packets to request additional data packets from the USB device compared to those requested by the host device. In some embodiments, the DFP device is configured to store a request packet in a packet queue if the request packet is received from the UFP device while the DFP device is busy receiving a response to a previous synthetic request packet from the USB device.
