You might be able to configure your desktop environment (e.g., GNOME, Unity, MATE, Cinnamon, etc.) to perform a certain action when a usb drive is plugged in. I use Cinnamon and when I insert a removable drive, Cinnamon asks me what I want to do with the drive. You might be able to select an option where you can tell it what command to run.

For the not faint of heart, you could dabble in udev rules. A more thorough example is on the askubuntu site.

In case the askubuntu page is not available, here is the text, edited only for formatting on this forum.

Thanks to MinimusHeximus and the respective contributors to the thread he mentioned in his comment to my similar question, I think I can now offer you the following answer.

You'll need 5 (five) files for such a USB device as follows, simply filling in respective values <fortheseparts>:

/etc/udev/rules.d/00-usb-<yourdevice>.rules

ACTION=="add", ATTRS{idVendor}=="<yourvendorid>", ATTRS{idProduct}=="<yourproductid>", ENV{XAUTHORITY}="/home/<user>/.Xauthority", ENV{DISPLAY}=":0", OWNER="<user>", RUN+="/usr/local/bin/usb-<yourdevice>-in_udev"   
ACTION=="remove", ATTRS{idVendor}=="<yourvendorid>", ATTRS{idProduct}=="<yourproductid>", ENV{XAUTHORITY}="/home/<user>/.Xauthority", ENV{DISPLAY}=":0", OWNER="<user>", RUN+="/usr/local/bin/usb-<yourdevice>-out_udev"


/usr/local/bin/usb-<yourdevice>-in_udev

#!/bin/bash
/usr/local/bin/usb-<yourdevice>-in &


/usr/local/bin/usb-<yourdevice>-in

#!/bin/bash
sleep 1
<yourbashscriptcode>


/usr/local/bin/usb-<yourdevice>-out_udev

#!/bin/bash
/usr/local/bin/usb-<yourdevice>-out &


/usr/local/bin/usb-<yourdevice>-out

#!/bin/bash
sleep 1
<yourbashscriptcode>


Notes:

1. You can capture the values <yourvendorid> and <yourproductid> by entering the command lsusb in Terminal -- when your USB device is plugged in -- which will list all your USB devices currently available, like Bus 003 Device 002: ID 8087:07da Intel Corp., where 8087 is the VendorID and 07da is the ProductID.
2. And <yourdevice> can be any arbitrary name you may choose for your USB device, for example, I chose to use the generic name "keyboard" when creating such files for my USB keyboard which required applying a different keyboard layout whenever it's plugged in.
3. In some scenarios, it may not be necessary to use the ACTION=="remove" line in the udev rules file, and hence the associated 2 (two) "out" files, when you don't need to do anything (e.g. reverse a change made when the device is plugged in) after the device is plugged out.
