摘要： Automatic protocol migration when upgrading operating systems includes checking, after upgrading at least a portion of an operating system of a host device, whether a new driver supporting enhanced functionality for a portable device is now available, where a driver supporting base functionality would have been previously used for communicating with the portable device. If such a new driver supporting enhanced functionality for the portable device is now available, then the host device installs the new driver supporting enhanced functionality for the portable device.

摘要： The various embodiments described below are directed to providing authenticated and confidential messaging from software executing on a host (e.g. a secure software application or security kernel) to and from I/O devices operating on a USB bus. The embodiments can protect against attacks that are levied by software executing on a host computer. In some embodiments, a secure functional component or module is provided and can use encryption techniques to provide protection against observation and manipulation of USB data. In other embodiments, USB data can be protected through techniques that do not utilized (or are not required to utilize) encryption techniques. In accordance with these embodiments, USB devices can be designated as “secure” and, hence, data sent over the USB to and from such designated devices can be provided into protected memory. Memory indirection techniques can be utilized to ensure that data to and from secure devices is protected.
摘要翻译：下面描述的各种实施例旨在从在USB总线上操作的I / O设备到主机（例如安全软件应用或安全内核）上执行的软件提供经认证和保密的消息传递。这些实施例可以防止在主计算机上执行的软件所征收的攻击。在一些实施例中，提供了安全的功能部件或模块，并且可以使用加密技术来提供对USB数据的观察和操纵的保护。在其他实施例中，USB数据可以通过不被利用（或不需要利用）加密技术的技术来保护。根据这些实施例，USB设备可以被指定为“安全”，因此，可以通过USB向这些指定设备发送和从这些指定设备发送的数据提供到受保护的存储器中。可以利用内存间接技术来确保进出安全设备的数据受到保护。

摘要： A client driver requests data packet transfers from a peripheral device through a protocol stack and a host controller. The protocol stack receives the data transfer request and allocates the request into the host controller schedule. The host controller schedule requests the data of the peripheral device, and directs the received data into previously allocated buffers. The host controller then sends a signal to the client driver that the respective buffers are filled. The host controller can then deactivate the instructions in the host controller schedule until further notice so that the instructions do not need to be deleted from the schedule. The client driver extracts the data from the buffer, and sends a signal to the host controller that the buffer can be used again. The request in the host controller schedule can then be reactivated without having to necessarily re-insert new instructions into the host controller schedule.
摘要翻译：客户端驱动程序通过协议栈和主机控制器请求从外围设备传输数据包。协议栈接收数据传输请求，并将请求分配到主机控制器调度中。主机控制器调度请求外围设备的数据，并将接收的数据引导到先前分配的缓冲区。主机控制器然后向客户机驱动程序发送一个信号，以填充相应的缓冲区。然后，主机控制器可以停用主机控制器调度中的指令，直到另行通知，以便不需要从调度表中删除指令。客户端驱动程序从缓冲区中提取数据，并向主机控制器发送一个信号，以便再次使用缓冲区。然后可以重新启动主机控制器调度中的请求，而不必一定将新指令重新插入到主机控制器调度中。

摘要： The following system and procedure for specifying an extended configuration descriptor includes a USB device that responds to device requests from a host. In response to receiving a host-specific device request that specifies a predetermined index, the USB device returns an extended configuration descriptor to the requester. The extended configuration descriptor includes information that can be used by the requestor to control the USB device. When the USB device is a composite device, the extended configuration descriptor includes function information corresponding to a plurality of sub-devices. Each function comprises one or more interfaces.

摘要： The invention described in the instant application provides for a failure-recovery module, which permits automatic investigation of possible reasons for the failure and takes corrective action in a manner transparent to the user. The failure-recovery module, which is a software module, is useful in evaluating a device connected to a master-slave bus to determine whether it has failed. In the event the device is still connected to the master-slave bus but is non-responsive, the failure-recovery module resets the device, e.g., by turning off the power to the affected device and rebooting the device with a cold start. The failure-recovery module diagnoses the failure of a device by determining if the device is still connected to the master-slave bus. Then, the failure-recovery module sets a flag to mark the device as having failed while disabling access to devices downstream of the failed device. If the failure-recovery module is unable to execute successfully, it assumes that the failure causing condition still exists. In some embodiments this results in rescheduling the execution of the failure-recovery module while in other embodiments a general failure may be declared or the failed device left in its disconnected state. On the other hand, if the failure-recovery module executes successfully, the affected device is reinitialized and the flags marking it as failed are cleared with access to the device being restored. Subsequently, downstream devices are reinitialized and resources, if available, allocated to them along with enumeration of the devices.
摘要翻译：本申请中描述的发明提供了故障恢复模块，其允许自动调查故障的可能原因，并以对用户透明的方式采取纠正措施。作为软件模块的故障恢复模块在评估连接到主从总线的设备以确定其是否失败时很有用。如果设备仍然连接到主从总线但不响应，则故障恢复模块会重置设备，例如，通过关闭受影响设备的电源并重新启动设备，并启动冷启动。故障恢复模块通过确定设备是否仍然连接到主从总线来诊断设备的故障。然后，故障恢复模块设置一个标志，以将设备标记为已失败，同时禁用对故障设备下游设备的访问。如果故障恢复模块无法成功执行，则假定故障原因仍然存在。在一些实施例中，这导致重新安排故障恢复模块的执行，而在其他实施例中可以声明一般故障或者故障设备处于其断开状态。另一方面，如果故障恢复模块成功执行，则受影响的设备将被重新初始化，标记为失败的标志将被清除，并访问正在还原的设备。随后，重新初始化下游设备，并将资源（如果有的话）与设备的枚举一起分配给它们。

摘要： A USB device is configured to support a non-USB-defined device request that is specific to an application program or operating system. The device request is supported by using a device-specific or vendor-specific request code, which is allowed to vary from device to device. To determine the proper request code, the host performs a GET_DESCRIPTOR device request, specifying a predetermined string descriptor. The requested string descriptor designates the request code to be used in the non-USB-defined device request.

摘要： The disclosure relates to an adjustable tool holder for a lathes or the like. A base block is secured to the lathe slide by a through bolt engaging a clamping bar in a Tee slot therein. A tool holding block is slideably mounted on the base block and also has a through-bolt extending through it and the base block and engaging the clamping bar. By loosening the second through-bolt and manipulating a micrometer adjustment screw, the cutting tool may be adjusted with great precision. The second through-bolt is then retightened to clamp the movable tool-holding block securely to the cross slide of the machine tool.

摘要： A continuous coater of the type having a conveyor extending through a coating booth where paint or other material is sprayed onto the products as they are conveyed through the booth. The booth has an air flow control vestibule located adjacent the entrance and exit ports. Each vestibule is connected to an air flow exhaust system and is so configured that it is operative to draw air almost exclusively from outside the booth into the exhaust system so that there is a minimum of input air to the exhaust system from within the booth. The incoming air from outside the booth effectively forms a flow barrier to the egress of sprayed material and/or solvent to the atmosphere through the vestibule entrance and exit ports. Preferably, there is located in each vestibule means for creating an air curtain which functions to minimize the egress of paint or solvent from the coater cabinet and to provide a more nearly saturated atmosphere inside the cabinet.

摘要： Quite a large cylindrical tube for a mouthpiece tube and a smaller stem for supporting a small bowl extend upwardly from different portions of a hollow base. The hollow base functions as a reservoir, and the base and the lower portions of the stem and the mouthpiece tube are filled with water. A plastic ball within the mouthpiece tube helps control the draw of the pipe. The plastic ball is the sealing member of the check valve that prevents rapid flow of water from the mouthpiece tube to the stem when inhalation is stopped abruptly. The port of the check valve is a hole that is eccentric within the bottom of the mouthpiece tube. The eccentricity provides a desirable amount of leakage for slowly equalizing the level of water in the mouthpiece tube and the stem.
