Linux UDEV Rule
In order for non-root users in Linux to be able to communicate with OnlyKey a udev rule must be created as described below.
Go to https://github.com/trustcrypto/trustcrypto.github.io/blob/master/49-onlykey.rules and download or create a copy of the file named 49-onlykey.rules into the Linux directory: /etc/udev/rules.d/ If this file is already there, ensure that the content looks like the one provided on the link above.
Use the command
udevadm control --reloador restart system for changes to take effect
To complete this via terminal issue the following commands:
$ wget https://raw.githubusercontent.com/trustcrypto/trustcrypto.github.io/master/49-onlykey.rules $ sudo cp 49-onlykey.rules /etc/udev/rules.d/ $ sudo udevadm control --reload
