I want to disallow usb port when it is connected.

I tried sys/bus/usb/devices/power/level=suspend but still, I can see that usb device and have access to that usb device. Please help me to stop access to a particular usb device which is connected to Linux system.

I also tried ioperm() but I cannot find usb port no. which is required for it. I am trying to do this by C++ programming.

I just typed "linux disable usb" into Google and noticed that it returned a number of possible answers.

It's amazing how many people can take the trouble to compose a question here, but seem incapable of composing a simple Google query. :(

Did you try the Google search I suggested? Are you actually capable of doing anything for yourself?
