USB port events linstening
Hi everybody!
I am a
complete newbie.
Is it possible to write a script (
shell or python) to listen to usb port event and to notify me every time an usb storage key is plugged or ejected? I want it to echo the device to mount (eg. /dev/sdb).
I wrote an udev rule wich runs a script after usb plugging but I don't know how to get the right device interface(eg. /dev/sdb) attached to my usb device.
The second problem is, how to get the right device interface if I plugged two or more usb devices? I'm lost.
Please, help me.
I'm working on a raspberry pi (without monitor).
Thanks.

twinstar
TWINSTAR(8) User Contributed Perl Documentation TWINSTAR(8)
NAME
twinstar - Control the Twinstar feature of a Xorcom Astribank
SYNOPSIS
twinstar {status|jump|enable-wd|disable-wd|ports}
DESCRIPTION
twinstar is a tool to control the Twinstar (dual USB port) of a Xorcom Astribank. There is a single and mandatory argument which is the
command to run. That command operates on all the Astribanks connected to the system.
Technically all the commands are implemented using Dahdi::Xpp::Mpp which in turn uses astribank_tool. Thus using thus tool will require
root permissions or otherwise read/write permissions to the USB device.
The twinstar may be in watchdog mode, which means that it will jump to the remote host if it loses contact with the local host. This can
happen if the machine is powered down or hangs or even if the xpp drivers are unloaded. Which is why the standard twinstar scripts put the
Astribanks in twinstar mode on startup and remove it on normal shutdown.
An Astribank will only jump to the other host (either if asked explicitly or by the watchdog) only if there is a different Astribank
connected to the other port and running. Which is why all of this has no effect on systems that don't need this functionality.
The command are:
status
Shows the current status of all Astribanks. Note that it only shows Astribanks whose current active USB port is the one connected to this
computer.
Example output:
DEVICE PORT WATCHDOG POWER0 POWER1
usb:001/010 0 on yes yes
usb:001/011 0 on yes yes
For each Astribank on the system that has Twinstar support we get:
Device
The address of the device. This is the bus address, e.g. the address you see in lsusb / dahdi_hardware.
Port
The active USB port on the Astribank. This should be always '0' on the master and always 1 on the slave.
Watchdog
on if the watchdog is triggered in the Atribank or off otherwise.
Power0, Power1
Shows which ports of this Astribank are connected to a USB port of a running computer. This only shows whether or not the USB host
provides power.
ports
Shows the same 'Port' column of the status command.
jump
Command all the Astribanks to jump to the other port. This works regardless the watchdog mode is enabled or not. But requires that there is
power on the other port.
enable-wd
Enables watchdog mode.
disable-wd
Disables watchdog mode.
FILES
twinstar mostly uses astribank_tool which in turn mostly uses USB files under /dev/bus/usb .
