我有2个相同的HID USB设备，每个设备都有其自己的控制程序，每个程序如何知道那里有哪个HID设备？
[英]I have 2 identical HID USB devices, each one has it's own control program, how can each program know which HID device is theres?
问题描述
Is there a way to assign one HID device to a program and then another identical HID device to another program without each of them grabbing randomly the first HID device they enumerate? 
有没有一种方法可以将一个HID设备分配给一个程序，然后再将另一个相同的HID设备分配给另一个程序，而不必让每个HID设备随机获取它们枚举的第一个HID设备？ I'd need some kind of unique identifier. 我需要某种唯一的标识符。 Is there such thing? 有这样的事吗？ On windows xp/vista/7. 在Windows XP / Vista / 7上。

The port is your default enumeration value. 端口是您的默认枚举值。 Configure your code to allow explicit specification of the port. 配置您的代码以允许显式指定端口。
Depending on a uuid of a device is probably not going to give you the results you expect in the long run. 从长远来看，取决于设备的uuid可能不会为您提供预期的结果。
