Info (System Drive) Error

Hi guys! I need to check if there is some flash memory connected to my computer. I’m using Info (System Drive)
But when I send a bang to update, it blink RED, and the TTY Render tell me:
ERR : Exception occured in TMPluginWrapperNode.Evaluate: The device is not ready.

Enabling the /showexceptions, I got this really really long message, you can see in the attached log

Can this let my patch crash? (must say, the node is working well)
There is a solution, or different way to obtain the list of driver connected to my computer?

There isn’t any different way to know if someone is connecting a flash memory to the computer?
