[opensuse] USB serial port on HP T1000 G3 UPS ?
I'm trying to use the HP Power Manager software which appears to require/expect a USB serial port when talking to the HP T1000 G3 UPS. The UPS _is_ connected via USB. The setup utility only works with /dev/ttySx but USB serial ports usually end up as /dev/ttyUSBx or in this case /dev/usb/hiddev0 .... -- Per Jessen, Zürich (21.1°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Did you try ln -s /dev/usb/hiddev0 /dev/ttySx ? HTH, Werner -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hi Werner yes, I did try that one, but the setup utility doesn't recognise it as a serial port: # LD_LIBRARY_PATH=$PWD ./DMSetup -log Shutting down UPS Device Manager Service: done.

ttyS0 is a real serial port, which I tried too - there's no UPS connected, but the utility seems to recognise it as a serial port.
So, /dev/ttyS0 is a real port. Are the other mentioned ports also real? Do they exist (ll /dev/tty*) or are they only a proposal from the UPS manager? If they do not exist, link the port you connected your UPS to (you mentioned /dev/usb/hiddev0) to one of the non-existing ports in that list.

Yep, that's what I did - ttyS9.
Ah, I see. Do you have the makedev package installed? If not, "zypper in makedev" an reading "man 8 makedev" may help. I think the "update" option looks promising. Or you use "mknod" to create /dev/ttyS9 manually, with the same parameters (major, minor, ...) as /dev/usb/hiddev0 has. So both devices should point to the same hardware... Or you find the file in /etc/udev/rules.d/ that is responsible for your /dev/usb/hiddev0 device, and add something like 'SYMLINK+="ttyS9"'.

Nooo.. Werner, you are giving all sorts of bad or really outdated advice.. you should not use makedev or any other sort of hack for dealing with device nodes.. nor use "ln -s" nor anything else than writting proper udev rules. It won't work. This is the deal: - If the package used to manage this UPS is included in the distribution, it has to be fixed to just work. - If this package is not part of openSUSE, you need to provide udev rules suitable for the task. Nothing else will really work and will break more soon than later. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Unfortunately, it is not.

The question seems to be - this software recognises /dev/ttyS0 as a "genuine" serial port (and attempts to talk to the UPS with that), but refuses to work with /dev/usb/hiddev0 no matter what I do. -- Per Jessen, Zürich (20.6°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The software in question, seems to be broken, it has to enumerate USB devices, filter them by class, vendor and by a list of specific ids, then attempt to communicate with the matching devices. Apparently you will have better luck using Network UPS Tools (NUT package) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
You gave to edit the config file in /etc/apcupsd/ named apcupsd.conf The entry is UPSCABLE usb Working perfectly with my APC Back-up RS 800 On Sun, Aug 11, 2013 at 12:42 PM, Cristian Rodríguez <crrodriguez@opensuse.org> wrote:

Yes, I tried that too - I removed the original /dev/ttyS9, then mknod'ed a new one with the same major/minor as /dev/usb/hiddev0 - no improvement on the situation. -- Per Jessen, Zürich (20.9°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
