I am trying to ascertain whether the radarbox USB device is connected on linux. I want to check this to detect in my perl program whether someone has pulled the device from its USB socket.
when I first insert it into the USB port, a `/dev/swradio0` is created. however, that device disappears at some point, even though the radarbox usb stick is still connected and working well.
is there a simple file system check to accomplish this?
Maybe you can use the lsusb command in a time interval to detect whether stick is connected.
To get just the device you want, you can use the command lsusb -d yyyy.zzzz
If this command returns empty, the USB is probably not connected.
Remember to replace yyyy.zzzz with the USB id found in the command lsusb
