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
2010-03-25 23:20:59 +00:00
bcmxcp_usb driver. For information about the core driver, see
2011-01-26 09:35:08 +00:00
linkman:nutupsdrv[8].
2010-03-25 23:20:59 +00:00
This driver is a variant of the serial driver bcmxcp and uses the same core code.
2011-01-26 09:35:08 +00:00
SUPPORTED HARDWARE
------------------
This driver should recognize all BCM/XCP-compatible UPSes that are connected
2010-03-25 23:20:59 +00:00
via USB. It has been developed and tested on Powerware PW3501 hardware. It also has
been tested on PW5110 hardware.

EXPERIMENTAL DRIVER
-------------------
2010-03-25 23:20:59 +00:00
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.
2011-01-26 09:35:08 +00:00
INSTALLATION
------------
2010-03-25 23:20:59 +00:00
This driver is not built by default. You can build it by using
2011-01-26 09:35:08 +00:00
"configure --with-usb=yes". Note that it will also install other USB
2010-03-25 23:20:59 +00:00
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 ...).
2011-01-26 09:35:08 +00:00
IMPLEMENTATION
--------------
2010-03-25 23:20:59 +00:00
bcmxcp_usb only supports 1 UPS at this time. You can put the
2011-01-26 09:35:08 +00:00
"auto" value for port in `ups.conf`, i.e.:
2010-03-25 23:20:59 +00:00
[pw3105]
driver = bcmxcp_usb
port = auto
2011-01-26 09:35:08 +00:00
KNOWN ISSUES AND BUGS
---------------------
"Got EPERM: Operation not permitted upon driver startup"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2010-03-25 23:20:59 +00:00
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.
