iSerialNumber does not need to be unique per device - it is not very many bits wide. I?m pretty sure I don?t *need* iSerialNumber?I mean, I could just remove it from the report descriptor altogether. But since it is available to give, and we are writing each board?s serial number into flash as part of the micro-controller programming (we aren?t talking a staggering number of boards per year

No, just as a variable string descriptor. By ?variable string descriptor?, do you mean what is contained in the example in the App Note? I?m just asking for clarification, in case variable string descriptor is something different than shown there. The way they do the string descriptors in the example is how I have mine now. They return a size and address, but it is to something that was

I found something particularly strange while trying out different things: I started up upsdrvctl, upsd, and upsmon. I then stopped upsdrvctl, and tried starting the usbhid-ups driver a few times. Each time I executed the driver, it indicated an instance was already running, stopped it, and then started it again....which is what it should do. I then added -DDDD to the command....and then it

What kernel version on openSUSE? --

For fun, if you want to see where the system thinks it is linking a library from, you can use "ldconfig -p" and it will give you a path to all known libraries that it can find. If you have one loaded, and it can't find it (odd directory, etc.) you can always amend "LD_LIBRARY_PATH" the same way as PKG_CONFIG_PATH I mentioned earlier . . . . PKG . . . is for the build

Usually I'd say run that as root when the driver isn't running,

I'm doing testing of the UPS-side code, including being able to tell the UPS to shutdown and then come back up after a while (if power has returned). I'm trying to use upscmd so that I don't have to do an actual shutdown, but when I have it list the commands for my UPS, I just see 4 commands, and they're not the ones I thought I had specified. load.on load.off shutdown.return

Rob - Just stepping in from the sidelines . . . with a few tidbits. Nut uses pkgconfig to find and identify stuff as part of it's build . . . So, depending on where your libusb install went, if it wasn't in the default "PKG_CONFIG_PATH" setting, it won't be found. Much like other shell variables, you can adjust that setting to find anything you like . . . IE

I am running tests on my system and UPS, making sure that it is reliably able to come up, detect power loss, shutdown safely, and then come back up when the power returns. It does that MOST of the time. However, a significant part of the time, the system comes up, and then doesn't respond to loss of power. Doing some checking, I find that the reason is because upsd never started. Capturing

And now....suddenly, and so far unexplainably....it works again. I did the same as before, installed openSUSE 13.1 from scratch, then installed the libusb* libraries. And now...it works, so far reliably. I'm certain that there is some micro-step I started doing different than last time. For example, I used to install jedit from the command line after install, but I had started installing

Ok, I tried this from scratch on a fresh 2.7.2 directory. I followed the web instructions, specifically: + I generated the new subdriver for my UPS (rtd-hid.*) based on PATH info. + I put them in the drivers subdir + I added the include line (#include rtd-hid.h) in usbhid-ups.c (specifically in the #ifndef SHUT_MODE section) + I added &rtd_subdriver, to the subdriver_list in usbhid-ups.c

The serial number of the unit (iSerialNumber according to the USB HID doc) is a constant, but it?s of course a different constant for each UPS. iSerialNumber does not need to be unique

I had thought that putting in my *.c and *.h files and making the makefile changes and then executing ./configure for the first time would be enough. Each tool serves a different purpose. autoreconf (and NUT's autogen.sh, by inclusion) generates the ./configure
