如何逆向工程 USB/HID/蓝牙加密狗。使用什么工具？答案

【问题标题】：How to reverse engineering USB/HID/BlueTooth dongle. What tools to use?如何逆向工程 USB/HID/蓝牙加密狗。使用什么工具？
【发布时间】：2014-04-01 23:48:13
【问题描述】：

需要对蓝牙usb鼠标加密狗进行逆向工程，并使用鼠标板测量距离，并用matplotlib绘制它们

我发现这些工具可以帮助完成这项任务：

Linux

lsusb
usbmon
usbhid 转储
射频通信
hidrd 转换
xxd
hcitool
evdev 转储

Windows

usblyser

【问题讨论】：

您想对功能进行哪些更改？如果您只想获取数据作为任意输入而不是“鼠标”移动，您可以告诉驱动程序忽略此设备，使用驱动程序代码作为如何读取它的参考，并在用户空间中执行此操作。或者您可能会告诉系统忽略该鼠标并自己声明它。您实际上不太可能需要对 dongle 进行“逆向工程”，因为它的功能应该符合标准预期。
@ChrisStratton，是的，我只需要移动鼠标。您能否发送一些关于“使用驱动程序代码作为如何阅读的参考，并在用户空间中执行此操作”的参考资料。所有这些都是相关的“写作驱动程序”，对吧？
"你只需要鼠标移动" ?它是哪一个 - 您需要将动作呈现为鼠标，还是需要将它们呈现为 而不是 鼠标？无论您走哪条路，您都必须自己进行研究和编程，但如果您最终需要复制现有驱动程序，请花时间研究它。
我需要转换鼠标移动来测量距离。这是我要构建的传感器chest strap sensor:link。然后用matplotlib:link 绘制这些数据
