Peter, Here are the transitions that I have tested with your latest changes (on the APC/Back-UPS ES 650): 1) OL ==> OB DISCHRG followed by OB DISCHRG ==> OL (no CHRG inbetween) 2) OL CHRG ==> OL 3) OL CHRG ==> OL CHRG LB (by manipulating battery.charge.low) 4) OL CHRG LB ==> OL CHRG (i.e. transition from below) 5) OB DISCHRG ==> FSD OB DISCHRG LB followed by proper shutdown In

Ladies and Gentlemen, I have been playing around with Arnaud's new HAL stuff a bit, and have some questions and observations. First my configuration: my UPS (Peter may remember): ups.mfr: APC ups.model: Back-UPS ES 650 ups.productid: 0002 ups.firmware: 818.w1.D ups.firmware.aux: w1 kernel: 2.6.18-92.1.6.el5 hal-0.5.8.1-35.el5, nut based on nut-2.2.2.tar.gz, small changes to

Peter, You may want to have a look at the comments to Bug 164524 at bugzilla@redhat.com: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=164524 I filed this a long while ago, because of the mess we get into when shutting down Linux via /etc/rc.d/init.d/halt, and the UPS device no longer being reachable when we want shut it down. There seem to be some changes to libusb on the way, that

Thomas, The none (-22) message in your log is an errno from the libusb_get_interrupt() call in HIDGetEvents() in libhid.c. It indicates an invalid ioctl type. In HIDGetEvents() there is a comment with that call: /* needs libusb-0.1.8 to work => use ifdef and autoconf */ You may want to make sure your libusb is up-to-date. Hope this helps, AG --

Gentlemen, I have now had a chance to run some initial tests of my changes to apc-hid.c of the current development tree. Running newhipups and inspecting the -DDDD output seems to indicate that with the fix below everything seems to work as expected. However, I have not yet shut my system in order to take the UPS out of action so that I can do my various tests with a lightbulb load. I still hope

Gentlemen, I am making progress with with my APC USB device. However, I have encountered a problem with the current build for newhidups. The problem is that on my system libusb.so resides in /usr/lib, which at the end of the shutdown sequence is no longer available. I believe that this is probably a relatively generic problem, and I think that the proper solution is to link all usb drivers

Gentlemen, On several occasions now I would have liked to start a complete set of (newhidups + upsd + upsmon) in the background, but with significantly more output to syslog. From a cursory look at the code, it looks to me that it might be easy to add an option similar to -D that doesn't stop putting the process into the background. I understand that higher levels of debug would create a

Gentlemen, I have determined that on my UPS (APC Back-UPS ES 650 FW:818.w1.D USB FW:w1), the variable UPS.PowerSummary.RemainingCapacityLimit is writeable. I am setting this variable to start shutdown a little earlier. Appended is an unconditional patch for apc-hid.h. If, as indicated by the original code, there are APC UPS devices that don't allow setting of this variable, it becomes

Gentlemen, I assume this is really for Arnaud: I am looking at the code in upsdrv_updateinfo() where it is processing a HID notification, i.e. it is not doing a full update: Question one, is it implicitely assumed that ups.status related items will always require a translation (i.e. item->hid2info != NULL) in order to be effective? I haven't seen any place where that is enforced, but

Gentlemen, As reported earlier, my UPS burps a lot of unsolicited interrupt messages. I have made some experiments with the UPS using newhidups directly, and noticed that the poll frequency of the dstate_poll_fds() calls in main.c can be heavily skewed by the timeout provided in the libusb_get_interrupt() call in libhid.c (currently 5 sec!). For a UPS that provides few interrupt messages, this

Gentlemen, This is probably for Arnaud, since he has already addressed a somewhat similar problem. I am running newhidups from the development tree (actually everything is from there). However, I have observed the same problem with a 2.0.2 system as well. Here is what I observe: * upsc shows the ups.status: is "OL" * there is a very short interruption of power * upsc shows the

Ladies and Gentlemen, Running newhidups with -DD shows the following line that starts with "-> String:" occasionally, with no contect that it is related to: ...... Can't find object UPS.Battery.Temperature -> String: PbAc (len = 4/4) Can't find object UPS.Output.PercentLoad ...... However, running newhidups with -DDD, shows the proper context: ...... hu_find_infoval:

Charles, When sorting out the library problem for shutdown, please also keep in mind that the shutdown scripts (at least those that I have encountered so far) insist on unmounting /dev/usb. This requires that libusb does not rely on its presence to do the reconnection for the shutdown. I don't know if this is a part of the definition of the functionality of libusb and if it can safely be

Gentlemen, I just had time to start looking at the latest version of the development tree. I have built the apc-hid part of newhidups from the development tree and I am in the process of testing it with my "Back-UPS ES 650". As of right now I have incorporated the attached changes to apc-hid.c. I have been using the corresponding changes together with some changes from Arnaud with the

Peter, Just to let you know that I have done all my tests with the latest development stuff (Oct 3 23:46 to be specific, with NO local patches!), and everything turned out fine except for the cleaning up of ups.status: as presented by upsc that I reported earlier. I suspect that that cleanup is generic to newhidups, because a couple of month ago Arnaud made some changes for cleaning up LB

Peter, Thanks a lot for your latest changes to newhidups, which I like a lot. Unfortunately, when I tried to build the latest development tree stuff, I got a compile time error when compiling al175.c. It looks to me like my compiler, gcc-3.4.4-2.fc3, doesn't like the macro definition for "RECV(reg) do" because of a poorly inserted comment. I fixed the problem locally by the

Gentlemee, I have just encountered a problem with low battery status in newhidups. Here is the situation: 1) The system goes through the shutdown sequence due to low battery, the UPS receives the shutdown.return and shuts off power, 2) After power returns, the UPS turns on power before its battery reserves have reached low battery level (a potentially risky situation if we get another

Peter, I just saw Scott Alfter's report. I just wanted to say that this is such a nice addition, I like it very much, it makes finding what is needed so much easier! One suggestion if I may, a timestamp of some kind with each =>Got line might be helpful for determining the notification frequencies. Thanks for the new option, AG --
