摘要： The present invention provides a USB peripheral device belonging to a model line of identical peripheral devices. The peripheral device includes a USB interface enabling connection of the peripheral device to a USB port of a host device. The peripheral device also includes a memory for storing a USB device identifier. The USB device identifier comprises a standard USB device identifier that is the same for all the peripheral devices of the model line. The standard USB device identifier identifies each peripheral device in the model line to the host device as identical devices, thereby preventing device driver reinstallation and communication port reassignment when swapping one peripheral device for another peripheral device from the same model line. This enables identical peripheral devices to be “hot-swappable” such that they can be interchanged on the host device, even when the host device is powered up and running. Corresponding methods are also provided.

摘要翻译： 本发明提供属于相同外围设备的模型线的USB外围设备。 该外围设备包括一个USB接口，使外围设备能够连接到主机设备的USB端口。 外围设备还包括用于存储USB设备标识符的存储器。 USB设备标识符包括与模型行的所有外围设备相同的标准USB设备标识符。 标准USB设备标识符将模型行中的每个外围设备识别为主机设备作为相同设备，从而在从同一型号线路切换另一外围设备的一个外围设备时，防止设备驱动程序重新安装和通信端口重新分配。 这使得相同的外围设备能够“热插拔”，使得它们可以在主机设备上互换，即使主机设备通电并运行。 还提供了相应的方法。
