Path and Prefix for Device Files (<devprefix> Section)
<Devprefix> section defines the prefix for the device name used by the daemon. For example, if prefix is "/dev/vsp/vspd" then the daemon will access device 0 as /dev/vsp/vspF0. We do not recommend you changing the value parameter unless necessary (and you know what you are doing). The section has the following syntax:
< devprefix value="/dev/vsp/vspd"/>
