Why cant I WinUsb_ReadPipe data from multiple identical devices in parallel?
this is a continuation of a problem I posted before. Here is the link...
Is it possible to use winusb to communicate with multiple identical usb devices simultaneously?
In summary, I have multiple identical devices and I need to continuously read from them in parallel. Firstly, I wrote a code that has each device running on a separate thread. This did not work out. After looking at the time each readpipe was accomplished I saw that they happened one after another. As by the advice, I went and implemented Overlapped structure into my code. However, that did not work either. I came out having the same issue. ( I take time after each read is finished ) After everything I decided to run two separate instances of my program. I took the time from each instances and combined them. After examining I saw that this issue still existed. Hence, I am wondering is this a limitation of winusb.sys itself?
Here is my link to my code...

Thank you very much, if something is unclear please tell and I will provide more information.
