BCMXCP_USB(8)                     NUT Manual                     BCMXCP_USB(8)



NAME
       bcmxcp_usb - Experimental driver for UPSes supporting the BCM/XCP
       protocol over USB

NOTE
       This man page only documents the hardware-specific features of the
       bcmxcp_usb driver. For information about the core driver, see
       nutupsdrv(8). This driver is a variant of the serial driver bcmxcp and
       uses the same core code.

SUPPORTED HARDWARE
       This driver should recognize all BCM/XCP-compatible UPSes that are
       connected via USB. It has been developed and tested on Powerware PW3501
       hardware. It also has been tested on PW5110 hardware.

EXTRA ARGUMENTS
       This driver supports the following optional settings in the
       ups.conf(5).

       shutdown_delay=delay
           The number of seconds that the UPS should wait between receiving
           the shutdown command and actually shutting off.

DEFAULT VALUES FOR THE EXTRA ARGUMENTS
       shutdown_delay =120

INSTANT COMMANDS
       This driver supports the following Instant Commands:

       shutdown.return
           Turn off the load and return when power is back.

       shutdown.stayoff
           Turn off the load and remain off.

       test.battery.start
           Start a battery test.

TODO LIST
       Report UPS alarm status
           BCM/XCP supports reporting a wide range of UPS alarm conditions.

       Report UPS statistics informations
           BCM/XCP supports reporting of UPS statistics data.

EXPERIMENTAL DRIVER
       This driver has been tagged experimental, even if it has been reported
       to be stable. Thus it is not suitable for production systems and it is
       not built by default. This is mainly due to the fact that it is a new
       driver.

INSTALLATION
       This driver is not built by default. You can build it by using
       "configure --with-usb=yes". Note that it will also install other USB
       drivers.

       You also need to install manually the hotplug files (libhidups and
       libhid.usermap), generally in etc/hotplug/usb/, to address the
       permission settings problem. Lastly note that the libhidups file must
       have execution flag set (ie using chmod +x ...).

IMPLEMENTATION
       bcmxcp_usb only supports 1 UPS at this time. You can put the "auto"
       value for port in ups.conf, i.e.:

           [pw3105]
                   driver = bcmxcp_usb
                   port = auto

KNOWN ISSUES AND BUGS
    Got EPERM: Operation not permitted upon driver startup""
       You have forgotten to install the hotplug files, as explained in the
       INSTALLATION section above. Don't forget to restart hotplug so that it
       applies these changes.
