It would be nice if attaching a thumbdrive to a cRIO / RT usb port triggered a "mounted" event or interrupt in the RT OS. Currently the only way to discover if a thumbdrive has been connected is to periodically run a file/folder info VI and see if one is present. It would be nicer if we could register a dynamic event and wait for it using an event structure, or similarily register for an interrupt event would work as well.
In my case, the use-scenario is a field maintenance person going out and manually plugging in a thumb-drive about once every 4 weeks to get the stored log files off of the controller. (No, we cannot use remote access in this case due to customer network restrictions.) So, in my case, I can easily use the polling solution, but if there is one thing I don't like to do, its to write polling code of any sort. It seems so wasteful. Other possible use cases could be to detect the presence of a thumb-drive and check for patch/updates, copy over new configuration files, etc.
