pyocd linux cannot find probe for CMSIS dap linker

On Linux, permission to access USB devices from user space must be explicitly granted via udev rules. This directory contains example udev rules to allow pyOCD to access common debug probes without requiring it to be run as root, something which is very highly discouraged.

 

$ sudo cp *.rules /etc/udev/rules.d
$ sudo udevadm control --reload

$ sudo udevadm trigger
changing highlighted for our CMSIS-dap link, the information can be got by dmesg while plug-in the device.
