Samba killed after disconnecting Usb Stick

[Fazoletti]

Every time i remove my usb stick from my wl-hdd smbd will be finished,
where can i disable this?
Is there any script that will be executed after inserting and removing an usb mass storage?

nvram set usb_smbenable_x=0
nvram commit

Samba will not start after inserting usb-stick and not finish after removing.
