# BCMXCP_USB(8)

## NAME

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

## SYNOPSIS

bcmxcp_usb -h

bcmxcp_usb -a UPS_NAME [OPTIONS]

Note | This man page only documents the hardware-specific features of the `bcmxcp_usb` driver. For information about the core driver, see nutupsdrv(8).

Note | This driver is a variant of the serial driver bcmxcp(8) 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.

Note | This driver does not currently support USB-matching settings common to other drivers, such as vendor, vendorid, product, productid, serial, device or bus.

## 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 information

  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 may be not built by default. This is mainly due to the fact that it is a new driver.

## INSTALLATION

This driver may be not built by default. You can require building it by using `./configure --with-usb=yes` (note that it will also install other USB drivers), or `./configure --with-drivers=bcmxcp_usb`. Either way, you would need libusb-dev (libraries and headers package) or equivalent for other platforms.

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.
