UPS on USB not detected

[lee]

Hi,

my UPS (HP T750 intl) which is plugged into an USB port with the
supplied USB cable is not detected. Nothing happens when I plug it out
or in, and I tried different USB ports. It´s the only USB device
connected, and lsusb only shows the host controllers but no USB
devices.

Other USB devices like card readers and USB disks work. Am I missing
some module?


***@yun:~# lsmod |grep usb
usbhid 14977 0
hid 32891 1 usbhid
usbcore 103361 3 usbhid,ehci_hcd,xhci

You're maybe missing the program to control your UPS unit (i.e., "nut" or
maybe the manufacturer's own utils, if available).

Before going with Nut, I would suggest you to look into the compatibility
table for UPS devices and verify your UPS brand and model is listed here:

http://www.networkupstools.org/compat/

If not present, perform a Google search to find out additional
information for setting up your device in linux.

Greetings,

Nut supports it via usbhid-ups. It´ll probably work once the UPS is
detected as USB device, so I figure the first problem that needs to be
solved is that the UPS isn´t detected at all.

Nothing in "dmesg"?

Does the unit attach a serial port?

***@yun:~# dmesg |grep -i usb
[ 8095.506188] usbcore: registered new interface driver usbhid

So I assume that the USB modules are all available and working, unless
I´m missing one.

Yes, and it came with the serial cable. But I don´t have a serial port
on my computer. Even if I had one, nut doesn´t seem to have support
for the HP T750 via a serial cable but only via USB.

If there´s some software supporting this UPS via a serial cable, I can
check if there´s a connector on the mainboard for a serial port, but
which software would that be?

How is that? Did you read it anywhere at Nut's site? :-?

"usbhid-ups" is the driver to be used, not the port. I mean IIRC, you can
define "usbhid-ups" as driver and "/dev/ttyS0" as serial port (or "auto"
for USB").

If there´s some software supporting this UPS via a serial cable, I can
check if there´s a connector on the mainboard for a serial port, but

Nut should be just fine. More difficult is to find nowadays a serial port
embedded in motherboard, they are becoming "extinct".

One can always try a USB-RS232 converter.

Sure, or even a PCI multi-port card.

I still need to make use of COM ports but there are not many
manufacturers embedding on their boards (heck, I would change 4 of my USB
ports -there are 12!- for 1 COM port) O:-)

Proc fs is not enabled. There are lots of entries under /sys. But if

Mmmm... man "lsusb" says it reads data from "/proc/bus/usb" :-?

How about loading a LiveCD of any distribution just to compare "lsusb"
output?

Yes, but that's only a driver's name. The same driver should be able to
handle different connection types (serial port and USB).

I have an APC Ups on my system, and it tells me when the power takes a
hit, and powers down the PC when the battery is going dead.. I have a
package installed to make that happen:
# dpkg --list |grep apcupsd
ii apcupsd
3.14.8-2 APC UPS Power Management (daemon)

As far as I could find out, apcupsd only supports UPSs made by APC,
perhaps some others, but not the one I have.

You're in luck. NUT in its stable compat supports the HP T750 intl with
driver usbhid-ups.

Install NUT and you're all set.

But usually I check what I see in stores (in Mexico) with NUT and I get
zip. APC is well supported with apcupsd but I never see it here.

what is the resukt of ls -l /dev/bus/usb/<bus number>/<device number>

I've dug into the protocol of about 5 UPSs in conjunction with a
consulting assignment. Each vendor has his/her own protocol which
varies widely from vendor to vendor but a single vendor typically has
the same protocol across its own product line.
