determine usb port

[mael15]

Hi,

I have a problem with this configuration:

How can I determine which USB 6210 device is on USB 1 together with the USB to RS485 converter? I communicate with the converter via CreateFile().

thanx!!

there is a way that i think it will work.. when you put usb in that port force labiew to send a little text file or something like this in that port then always send a file to the device that has this text .

don not connect both of them at once.

thank you. i forgot to write that i do not use labview but c++.

i solved this problem. just in case someone needs the solution: i was able to recursively loop through all usb hubs/devices using the winApi by tailoring this source code:
