hi i want to lock my usb port of system.i am using linux fedora 11 operating system. so for that purpose i want to know or i want the detection code that help to detect any external devices plug in to system.

If you want to disable the usb, you can do it in the follwing way:
Open /etc/modprobe.conf file and turn off auto loading by adding:

Then run:

is there any source code for this detection of devices

some udev rules might help..then you can run a program when certain device is detected

You could for example change ownership or permissions for that device

SUBSYSTEMS=="usb", DRIVERS=="usb",MODE="0600", OWNER="unics", SYMLINK+="usbdevice_%k"
the only usb device that I have is a floppy...

you can be more specific using ATTRS{some identification} ...I guess sky is the limit
you ca use string pattern matching etc etc
using external programs you can log all the usb devices conected, because udev variables can be accessed by external scripts

thank u sir ,.
but one question sir if i write external program for this how could i deal with this ?

This is the same question as:

• provide security to usb port
• about usb port
• about usb port
• usb problem plz solve

That's not nice -- it's against LQ rules for very good reasons like it wastes people's time answering a question that may already have been answered and it makes it harder for people searching later for solutions to a similar problem.

Please use descriptive titles, and do not say things like "please solve". I put in a better title.
Also, please do not use texting shorthand here---spell out you words and use caps, punctuation, etc.

Have you read up on things like hal and udev? What have you found on Google?
What does this mean?
