newbie question, but is there a way to disable USB ports on a machine running Endless?
We deployed a few of these machines as kiosks and I’d like to discourage users from plugging drives into them without me cementing them shut. 
Thanks in advance!
Hi there!
There is a way but, as far as I’m aware, only under the command line - can get tricky but I’ll show you an example.
Firstly, you need to open up a terminal and enter:
lsusb
this should give you a list of USB ports / hubs on your machine.
The bit you will be interested in is Device xxx - this is the device ID of any port / device you might want to turn off.
You can turn individual devices off with the following (replacing usbxxx with your device number without any leading zeros):
echo disabled | sudo tee /sys/bus/usb/devices/usbxxx/power/wakeup
echo suspend | sudo tee /sys/bus/usb/devices/usbxxx/power/level
The first line disables USB wakeup and the second disables the port itself.
To revert you should do the following:
echo enabled | sudo tee /sys/bus/usb/devices/usbxxx/power/wakeup
echo on | sudo tee /sys/bus/usb/devices/usbxxx/power/level
Test this on a non-production machine first until you are happy it is working as it should!!
Best of Luck!
Awesome, thank you so much! I will definitely try this out.
