+For an active/desktop user logged in via session manager it should be like:
 
     ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="2935", TAG+="uaccess"
 
+For a daemon configuration we should provide explicit permissions like:
+
+    SUBSYSTEM=="usb", ATTR{idVendor}=="2935", MODE="0660", OWNER="reprostim", GROUP="plugdev"
+
 Note: we can see that "ATTR{idVendor}" value 2935 is equal to one we got in 
 step 1) from lsusb utility.
