+**newRPL** devices can communicate with **newRPL Desktop** by connecting the calculator to the host with a USB cable. There's some additional steps needed on various operating systems in order to communicate with the calculator:
 **Windows**
 No additional steps needed, just plug it.
 **Linux**
-The current user (the user newRPL Desktop is running as) needs to have read/write permissions to USB devices.
-Create a new group ''usbdevices'', then add the current user to that group.
-Next, create a file (as root) ''/etc/udev/rules.d/50-HIDDevices.rules'', containing the following two lines:
+The current user (the user **newRPL Desktop** is running as) needs to have read/write permissions to USB devices.

+  - create a file (as root) ''/etc/udev/rules.d/50-HIDDevices.rules'', containing the following lines<code>
   KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="usbdevices"
   SUBSYSTEM=="usb", ATTR{bInterfaceClass}=="03", MODE="0664", GROUP="usbdevices"
+</code>This will indicate the system to assign the group ''usbdevices'' to all new HID devices, and permits read/write to members of that group;
-This will indicate the system to assign the group usbdevices to all new HID devices, and permits read/write to members of that group.
+  - finally, restart the system for the new permissions to take effect.
 **freeBSD**
-The current user (the user newRPL Desktop is running as) needs to have read/write permissions to USB devices.
-Create a new group ''usbdevices'', then add the current user to that group.
-Next, create a file (as root) ''/etc/devfs.rules'', containing the following:
-  [localrules=5]
-  add path 'ugen*' mode 0660 group usbdevices
-  add path 'usb/*' mode 0660 group usbdevices
-  add path 'uhid*' mode 0660 group usbdevices
-Finally, edit the file (as root) ''/etc/rc.conf'' and add a line at the end:
-  devfs_system_ruleset="localrules"
