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@xxxxxxxx>: > 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. > > Ashish Bunkar > Linux Engineering > Dell | BDC > office +91-80-28078131, mobile +91-7259183696 > Ashish_Bunkar@xxxxxxxx > > > > -----Original Message----- > From: kernelnewbies-bounces@xxxxxxxxxxxxxxxxx [mailto:kernelnewbies-bounces@xxxxxxxxxxxxxxxxx] On Behalf Of ??? > Sent: Tuesday, June 05, 2012 8:48 AM > To: kernelnewbies > Subject: How can I disable all USB devices? > > Hi there, > > I want to disable all my USB devices (mouse, keyboard,... ) now, but hope to enable some certain device in the future.
