你好

有没有一种方法可以通过指定连接到的USB端口从特定的USB条码读取器读取数据?我希望能够从该特定的USB端口专门读取.

我在这里找到这个项目
用于C#的USB HID组件 [

Hello

Is there a way to read data from a particular USB barcode reader by specifying the usb port it''s connected to? I want to be able to read specifically from that particular usb port.

I found this project here
A USB HID Component for C#[^]

but I am getting an error everytime i try to connect to the device because, according to them, the device is already connected or being used by another process.

Any help would be highly appreciated

推荐答案

条形码设备驱动程序可能正在使用它:请与您的手册或制造商联系，以便您可以联系通过驱动程序，通过某种形式的API来实现.

在不了解读者的情况下，我无法说出更多明确的信息！

It is probably in use by the Barcode device driver: Check your manual, or with the manufacturer, as you should be able to contact it via the driver, through an API of some form.

Without knowing more about the reader, I can''t say anything more definite!
