USB Mass-Storage Device on CompactRio 9025

[masterwho]

I'm trying to store data in the memory stick which is connected to the CompactRio 9025. The memory is formatted with FAT32 file system. That's should be all right.

It says that LabVIEW maps USB devices to the U:, V:, W:, or X: drive. But when I ran the VI to create a file on U: drive, the path returned by close file function is NOT A PATH. I also tried to use the other three drives, but it still doesn't work. And I cannot even find the above 4 drives on my CompactRio.

How could I fix this problem?

Thank you very much!

The first step is making sure the version of LV you are using supports this module.  Says here you need LV 2009, LV FPGA 2009, LV Real-Time 2009 and NI-cRIO 3.3 or newer.

Are you using forward slashes or backward slashes in the file path?  You should be using forward slashes "/".

Thank you for your reply.

I set the path to be U:\test.txt. Is that all right? Should I mak some configuration before I try to store data on the memory stick through USB port?

Thanks very much!
