What happened When I PLug a USB Disk Into WL-500g-x's USB port

[iamchating]

Hi

I am using Oleg's latest firmware

I am trying to do some modifitions to the USB Disk FTP function to enable it can read/write chinese file name


There seems to be a deamon that monitoring the usb port
if there is an USB disk plugged in
it runs a script,mount the disk and make some temporary files under /tmp


my question is

which file(s) is invoked during the above process?

Thx

I think it's the watchdog, but i'm not sure.
