Is there a way to check if a device is available?For example checking if a USB Serial device shown in the system as /dev/ttyUSB0 is actively seen by the system? I have tried # check for USB serial adaptor as USB0check filesystem USB_Serial0 path /dev/ttyUSB0 if changed fsflags then alert and # check for USB serial adaptor as USB0check filesystem USB_Serial0 path /dev/ttyUSB0 if not exist then alert
