  1. Hello, i am using an Odroid Xu4 in an open Access environment and i want to disable USB Keyboards. I already tried the following: Create a file called, e.g., usbhid.conf in /etc/modprobe.d/ and add the following line: blacklist usbhid Then re-generate your initramfs with: update-initramfs -u -k $(uname -r) or, if you want to rebuild the initramfs for all installed kernel versions: update-initramfs -u -k all After you reboot, usbhid.ko will be prevented from loading. But it doesn't work for me. I Also get an Error while trying to update initramfs dirtydroid@odroidxu4:~$ sudo update-initramfs -u -k all ln: failed to create hard link ‘/boot/initrd.img-3.10.104-odroidxu4.dpkg-bak’ => ‘/boot/initrd.img-3.10.104-odroidxu4’: Operation not permitted update-initramfs: Generating /boot/initrd.img-3.10.104-odroidxu4 /boot/initrd.img-3.10.103-odroidxu4 does not exist. Cannot update. After this was failing. I tried to remove the usbhid from the drivers. sudo rm /lib/modules/<your_kernel>/kernel/drivers/hid/usbhid/ But i don't find the usbhid anyhwere. Can u tell me which drivers I have to remove to disable usb keyboards? Or do u have any other suggestion how to ensure that no keyboards can be attached to the usb ports? I really appreciate any help u can provide.
