You could try this, although may cause other issues:

sudo sh -c 'echo "blacklist usb-storage" >> /etc/modprobe.d/blacklist.conf'

Solution 2

Just rename storage to storage-old:

mv /lib/modules/3.2.0-35-generic-pae/kernel/drivers/usb/storage /lib/modules/3.2.0-35-generic-pae/kernel/drivers/usb/storage-old

Do you want to disable USB storage devices? Why are you still using such an old Ubuntu?

My answer only applies for a specific set of circumstances. Why is it you want to disable a usb port, for what type of device, and are you trying to disable all usb ports or just one?

@david6 10.10 is not that old. Less than two years ago, after all. Some institutions are still using 8.04, which is a LTS; desktop support for it just ended last year, with server support ending now.

Define "disable". Do you want to remove the power or make Ubuntu ignore any USB device?

change the kernel revision with the kernel ver. you have

[david6]

Edit file /etc/modprobe.d/blacklist.conf, to remove line which that this added. ie. "blacklist usb-storage". You could use vim or gedit, from the command line. eg. sudo vim /etc/modprobe.d/blacklist.conf

@Sushantp606 We can! awk '!/pattern/' file > /tmp/temp && sudo mv /tmp/temp /etc/modprobe.d/blacklist.conf
