Fwd: How can I disable all USB devices?

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.
