Best Answer

You can make a udev rule that disables devices by default, but enables certain ones by vendor ID. Make a file /etc/udev/rules.d/01-usblockdown.rules that contains a rule to disable devices:

ACTION=="add", SUBSYSTEMS=="usb", RUN+="/bin/sh -c 'for host in /sys/bus/usb/devices/usb*; do echo 0 > $host/authorized_default; done'"

And then rules to enable the devices you want to allow (you can use ATTR{idVendor} to get at the vendor ID):

ACTION=="add", ATTR{idVendor}=="0000" RUN+="/bin/sh -c 'echo 1 >/sys$DEVPATH/authorized'"

See "Locking down Linux using UDEV" for more information.
