摘要： A keyboard selectively operable to convey data to and from a host or personal computer (PC) through a universal serial bus (USB) port and/or a personal system/2 (PS/2) port. The keyboard is preferably connected to both the USB port and PS/2 port on the host or PC, if available. Preference is given to communicating data from the keyboard to the host or PC through the PS/2 port. However, if the PS/2 port is unavailable, not connected, or inoperative, the keyboard data are communicated to the host or PC through the USB port (assuming that it is available, operative, and connected). As soon as the PS/2 port on the host or PC is again connected to the keyboard, such data will again be communicated through the PS/2 port. In addition, the keyboard includes auxiliary USB ports to which USB-capable peripheral devices can be connected. USB data can then be communicated between the PC and the USB-capable peripheral devices via the keyboard and its connection to the USB port on the host or PC. Power supplied from the PS/2 port on the host or PC is monitored to determine whether that port is connected to the keyboard, and in response, to cause data arising from the user actuating keys on the keyboard to be supplied to the host or PC through the PS/2 port.

摘要翻译： 键盘，其可选择性地操作以通过通用串行总线（USB）端口和/或个人系统/ 2（PS / 2）端口向主机或个人计算机（PC）传送数据。 键盘优选连接到主机或PC上的USB端口和PS / 2端口（如果有的话）。 优先考虑通过PS / 2端口将数据从键盘传送到主机或PC。 然而，如果PS / 2端口不可用，未连接或不起作用，则键盘数据通过USB端口传送到主机或PC（假设它可用，可操作和连接）。 一旦主机或PC上的PS / 2端口再次连接到键盘，这些数据将再次通过PS / 2端口传送。 此外，键盘还包括可连接USB功能的外围设备的辅助USB端口。 然后可以通过键盘和PC与主机或PC上的USB端口的连接，在PC和支持USB的外围设备之间传送USB数据。 监视从主机或PC上的PS / 2端口供电的电源，以确定该端口是否连接到键盘，并且作为响应，将由键盘上的用户启动键产生的数据提供给主机或PC 通过PS / 2端口。

摘要： A peripheral device is connectable to a computer having one of a first interface and a second interface. The first interface communicates with the peripheral device over a differential data connection having a first data conductor and a second data conductor. The second interface communicates with the peripheral device over a clock conductor and a single ended data connection which includes a data conductor. The peripheral device has first and second communication conductors configured for connection to the first and second data conductors in the differential data connection when the computer includes the first interface and is configured for connection to the first data conductor in the single ended data connection and the clock conductor when the computer is provided with the second interface. The peripheral device includes an interface detection component coupled to the first and second communication conductors and configured to detect which of the first and second interfaces the peripheral device is connected to. The peripheral device also includes a controller component configured to communicate between the peripheral device according to a protocol corresponding to the detected interface.

摘要： A peripheral device, connected to a computer, has either a first or second interface. The first interface communicates over a differential data connection and the second interface communicates over a clock conductor and a single ended data connection. The peripheral device has first and second communication conductors that are either connected to the differential data connection when the computer includes the first interface or to the single ended data connection and the clock conductor when the computer includes the second interface. The peripheral device has an interface detection component that detects which of the first and second interfaces the peripheral device is connected to. The peripheral device also has a controller that communicates according to a protocol corresponding to the detected interface.
