    • A game controller operates in both a wired mode and a wireless mode, and is able to switch between these two modes without permanent disruption to an ongoing game. During a transition from one mode to another, a host gaming system detects when the controller is physically disconnected (for wired mode to wireless mode) or connected (for wireless mode to wired mode). Upon detection, the host gaming system stores the game data and user information and the game controller stores an identifier in its nonvolatile memory. The host gaming system and game controller then establish a new communication link. The game controller retrieves the identifier and submits it to the host gaming system, which uses the identifier to reassociate the game data and user information with the game controller as it begins operating in the new mode. This allows the player to continue game play without interruption.
    • 游戏控制器在有线模式和无线模式下操作,并且能够在这两种模式之间进行切换,而不会持续中断正在进行的游戏。 在从一种模式转换到另一模式的过程中,主机游戏系统检测控制器何时被物理断开(用于有线模式到无线模式)或连接(用于无线模式到有线模式)。 一旦检测到,主机游戏系统存储游戏数据和用户信息,并且游戏控制器将标识符存储在其非易失性存储器中。 主机游戏系统和游戏控制器随后建立了新的通信链路。 游戏控制器检索标识符并将其提交给主机游戏系统,主机游戏系统在新游戏开始运行时使用该标识符将游戏数据和用户信息与游戏控制器重新关联。 这允许玩家继续游戏,而不会中断。

    • Systems and methods for controlling the rise and fall times of USB signals for USB devices and peripherals are provided. The rise and fall times of USB peripherals can be controlled, or changed, in order to match the electrical characteristics of the USB peripheral to a USB host. By sweeping through a range of rise and fall times, and testing the reliability of USB output, optimal rise and fall times for the characteristics of a USB peripheral can quickly be determined. In one embodiment, the controllability of the rise and fall times is provided in firmware that changes at least one characteristic of the USB peripheral that affects the amount of current flowing during USB signaling.
    • 提供了用于控制USB设备和外围设备的USB信号上升和下降时间的系统和方法。 USB外设的上升和下降时间可以被控制或改变,以便将USB外围设备的电气特性与USB主机相匹配。 通过扫描上升和下降时间范围,并测试USB输出的可靠性,可以快速确定USB外设特性的最佳上升和下降时间。 在一个实施例中,在固件中提供上升和下降时间的可控性,所述固件改变影响在USB信令期间流动的电流量的USB外围设备的至少一个特性。
