I am communicating with a device via USB and am using a method setup by the USB driver programmer. To communicate, I write to a binary file with a filename of \\?\COMx. This has been working fine for about a year in mfg with Labview 8.0. I recently "upgraded" to 8.2 and now it does not work. If I save for a previous version and run 8.0 it works fine. How can I make this work with 8.2?

LabVIEW

write to binary file different from 8.0 to 8.2?

Hi Don,
Were you talking to an Applications Engineer? Do you know the service request number? I'd like to touch base with them and be updated on the progress of this issue.
Thanks!
