使用WriteFile()发送隐藏报告 [英] Sending hid reports with WriteFile()

问题描述

我有一个正在开发的USB隐藏设备.
当我使用WriteFile()(Win32)发送报告时，只会收到其他所有报告. WriteFile在lpNumberOfBytesWritten参数中返回报告len +1，这是正确的(报告ID为+1，我将其设置为零).
我99％确信不是设备问题.

为什么只有其他所有报告都能通过?

[edit]
该设备具有中断输出端点，因此该端点在使用中，而不是ep0.

I have a usb hid device under development.
When I send a report with WriteFile() (Win32) only every other report is received. WriteFile returns report len + 1 in the lpNumberOfBytesWritten parameter, which is correct (+1 for the report id, which I set to zero).
I am 99% sure its not a device issue.

Any ideas why only every other report gets through?

[edit]
The device has an interupt out end point, so this end point in being used, not ep0.

感谢肯尼斯，我对它不是设备一事再三考虑.
