如何启用/禁用特定的USB端口 [英] How to Enable/Disable a particular USB port

问题描述

大家好，

我再次需要帮助.我被要求组装一个应用程序，该应用程序除其他外，必须具有启用条形码的部分.当然，这不是原始规格的一部分，大部分应用程序(98％)已完成.

这是场景；由于数据输入点太多(文本框，组合框和其他类似控件)，我希望能够检测是否已插入USB条码读取器，并能够禁用/启用USB条形码读取器.随心所欲的USB端口.

这样的事情有可能吗?

谢谢大家的关注和帮助.

Hello Everybody,

I am in need of assistance once again. I was asked to put together an app that among other things, must have a barcode enabled section. Of course, this was not part of the original specs and most of the app (98%) is done.

Here''s the scenario; since there are so many data entry points (textboxes, comboboxes, and other similar controls), I''d like to be able to detect if the USB barcode-reader is plugged in or not, and to be able to disable/enable the USB port where it is at will.

Is such thing even possible?

Thank you all for your interest and help.

Joe.

你好kaushikjoshi，

谢谢您的建议.乍一看，它似乎仅提供有关已连接设备的信息，而不是提供启用/禁用特定设备的选项，但我将对其进行更深入的研究.也许确实有我需要的东西.

我会告诉您是否有帮助.

最好的问候.

Hello kaushikjos

Thank you for your suggestion. At a glance it seems to only offer information on connected devices rather than offering the option to enable/disable a particular one, but I''ll look closer into it; perhaps it does have what I need.

I''ll let you know if it was helpful.

Best regards.
