Detect USB Stick insertion

[Kyle Thompson]

I am trying to write a LabVIEW app that will be able to detect that a USB stick/key has been inserted into the computer. I know that I can get the names and serial numbers of all the drives that are currently mounted. However, I do not know how to check to see if one of them is a USB mass storage device, more specifically a USB stick as opposed to a USB-attached optical drive.

I could just check the size of the device and if it is under 4GB assume that it is a USB key. But if there is a more elegant way of doing it that I can be more sure of, I would like to do it.

Using LabVIEW 8.2.1

You could try the VI mentioned in this LAVA thread.

Or, you can try this C# class.

Thank you. I think I am just going to go with the polling with the list directory VI every 100 ms or around that. Just compare the new list of drives to the old ones, if there is a new one I will take the action that I want.

I think the environment is controlled enough that we won't have issues with that. No one will be swapping drives out like mad (or at least they shouldn't be!).

Hello,

I need to detect the USB stick insertion in cRIO RT 9014? List Directoy/Folder does not list the driver names in cRIO. It lists the ni-rt folder only. How do I detect the USB stick insertion and copy a file to the USB memory from cRIO RT.

Thanks in advance.

Hi A. Senthilnathan,

The USB stick insterted in your cRIO RT 9014 will show up as the u:/ drive. To access it, you can ftp into the cRIO by going to ftp://xxx.xxx.xxx.xxx/u😕 .

Thank you for choosing National Instruments.

This is my problem too (Detect USB Flash inserting)

But your program does not work. Does it ? I got an error while opening it by LV2010

To monitor USB devices I would recommend using this C# Class as recommended above.  Good Luck
