Thanks for reply! But it seems not suitable for my job. Sorry for that I didn't talk about my situation clearly. I was asked to only enable usb Network Interface Card, and disable all other usb devices(like keyboard, mouse, stick, etc.). I need a way to distinguish different usb devices and disable/enable them. If anyone has some idea, please tell me. 2012/6/5 <Ashish_Bunkar@dell.com>:
Hi
You can just disable the USB support for your kernel by editing kernel parameters. Just add "nousb" to you kernel parameters In "/etc/grub.conf" and your kernel should not support USB device thereafter. Also when you would like to enable them again just remove "nousb" from kernel command line and all should work fine with that.
Please let me know if that helped you.

Hi there,
I want to disable all my USB devices (mouse, keyboard,... ) now, but hope to enable some certain device in the future. And I don't want to recompile kernel or disable usb module.
I've searched on the Internet, and it seems that udev manage devices connecting to my computer. Can I use udev to disable all USB devices?
Thanks!
