是否有带时间戳的USB信号寄存器？ [英] Is there a USB signal register with time stamp?

问题描述

我只是想知道USB连接，如果我关闭了PC并在PC关闭位置插入USB，之后就会启动PC，计算机会在启动方案中注册USB插入，以及在Windows中注册的位置吗？



我想知道我的USB已离开我的电脑或已插入我的电脑此日期，20161026 intill 20161124任何驱动程序日志，需要帮助才能找到它的痕迹。

驱动程序日志可能吗？



它有点像精简有点......在计算机上不太好用的是log paser下载程序吗？

因此USB的驱动程序不是一个解决方案在？



问候



Anders



我尝试了什么：



免费软件USB forencis，但我不会得到所有的邮票历史。

Hi,

I just wonder about the USB connection, if i got the PC in off and plug in the USB in PC off position and after that will start the PC, will the computer register that an USB is pluged in in the start up scenario, and where will in registrated in windows?

I would like to know if my USB have left my computer or have was inserted in my computer at this date, 20161026 intill 20161124 any driver log, need help to find trace of it.
Driver log maybe?

It lok like lite bit tricky...Not so good on computer, is log paser a download program?
So the driver for USB is not a solution to look at?

Regards

Anders

What I have tried:

Free ware USB forencis, but i will not get all the history of stamp.

推荐答案

初始设备检测由USB集线器执行。当设备连接到集线器的下游端口时，它会更改集线器检测到的数据线级别，存储并发信号通知主机。然后，主机与集线器通信以执行设备的进一步初始化。完成后，主机可以直接与设备通信。



当打开PC时，它的工作方式相同。集线器通电后，它将启用USB线路上的电源，这将使连接的设备通电并在集线器上注册。然后，主机向集线器查询连接的设备并开始进一步初始化。



启动时，初始设置不是由操作系统执行，而是由BIOS执行（例如，允许使用USB键盘和鼠标更改BIOS选项）。



操作系统稍后将开始与所有集线器通信，发送重置命令以触发已连接的每个设备的重新初始化。



这样的重置可以随时进行（重新扫描USB设备）。



没有特定的时间戳寄存器。由控制主机（BIOS和操作系统）的软件来存储事件的时间。



另见USB.org - 文件 [ ^ ]和 NutShell中的USB - 第1章 - 简介 [ ^ ]。

Initial device detection is performed by USB hubs. When a device is connected to a downstream port of a hub, it changes the data line level which is detected by the hub, stored, and signaled to the host. The host then communicates with the hub to perform further initialisation of the device. Once that is finished, the host can communicate directly with the device.

When switching a PC on it works the same way. Once the hub is powered, it will enable power on the USB lines which will let attached devices power up and register at the hub. The host then queries the hub for attached devices and start further initialisation.

At power up the initial setup is not performed by the operating ystem but by the BIOS (e.g. to allow changing BIOS options using USB keyboards and mice).

The operating system will later upon starting communicate with all hubs sending a reset commands to trigger re-initialisation for every device already connected.

Such reset can be done anytime (re-scan USB devices).

There is no specific timestamp register. It is up to the software controlling the host (BIOS and operating system) to store times of events.
