NAME
riello_usb - Driver for Riello UPS Protocol UPS equipment via USB
SYNOPSIS
riello_usb -h
riello_usb -a UPS_NAME [OPTIONS]
Note
|
This man page only documents the hardware-specific features of the riello_usb driver. For information about the core driver, see nutupsdrv(8). |
SUPPORTED HARDWARE
riello_usb supports all recent Riello UPS with USB.
Older Riello UPS products are not supported.
EXTRA ARGUMENTS
- port = string
-
Some value must be set, typically auto.
NoteThis could be a device filesystem path like /dev/usb/hiddev0
but current use of libusb API precludes knowing and matching by such identifiers. They may also be inherently unreliable (dependent on re-plugging and enumeration order). At this time the actual value is ignored, but syntactically some port configuration must still be there.
It is possible to control multiple UPS units simultaneously by running several instances of this driver, provided they can be uniquely distinguished by setting some combination of the vendor, product, vendorid, productid, serial, bus and/or device options detailed below. For devices or operating systems that do not provide sufficient information, the allow_duplicates option can be of use (limited and risky!)
- vendorid = regex
- productid = regex
- vendor = regex
- product = regex
- serial = regex
-
Select a specific UPS, in case there is more than one connected via USB. Each option specifies an extended regular expression (see regex(7) for more information on regular expressions), which must match the UPS’s entire respective vendor/product/serial string (minus any surrounding whitespace), or the whole 4-digit hexadecimal code for
vendorid
andproductid
.Try lsusb(8) or running this NUT driver with -DD command-line argument for finding out the strings to match.
Examples:
-
-x vendor="Foo.Corporation.*"
-
-x vendorid="051d*"
(APC) -
-x product=".*(Smart|Back)-?UPS.*"
-
- bus = regex
-
Select a UPS on a specific USB bus or group of buses. The argument is a regular expression that must match the bus name where the UPS is connected (e.g.
bus="002"
orbus="00[2-3]"
) as seen in/proc/bus/usb/devices
or lsusb(8); including leading zeroes. - device = regex
-
Select a UPS on a specific USB device or group of devices. The argument is a regular expression that must match the device name where the UPS is connected (e.g.
device="001"
ordevice="00[1-2]"
) as seen in/proc/bus/usb/devices
or lsusb(8); including leading zeroes. Note that device numbers are not guaranteed by the OS to be stable across re-boots or device re-plugging. - allow_duplicates
-
If you have several UPS devices which may not be uniquely identified by the options above (e.g. only VID:PID can be discovered there), this flag allows each driver instance where it is set to take the first match if available, or proceed to try another.
Normally the driver initialization would abort at this point claiming "Resource busy" or similar error, assuming that the otherwise properly matched device is unique — and some other process already handles it.
WarningThis feature is inherently non-deterministic! The association of driver instance name to actual device may vary between runs!
If you only care to know that at least one of your no-name UPSes is online, this option can help.
If you must really know which one, it will not!
- usb_set_altinterface = bAlternateSetting
-
Force redundant call to
usb_set_altinterface()
, especially if needed for devices serving multiple USB roles where the UPS is not represented by the interface number0
(default).
