matteobp Posted September 30, 2018 Share Posted September 30, 2018 Hi. I have a Odroid XU4 with Ubuntu Bionic latest release (5.60), powered with this UPS: APC SmartUPS 750 VA.Apcupsd doesn't work. The problem seems related to the missing /dev/usb/hiddev0. After searching on Google, I found that apcupsd requires this feature enabled in the kernel.CONFIG_USB_HIDDEV=Y I build my own kernel enabling it, but no change. Here the output of the command # dmesg | grep Smart [ 4.125553] usb 1-1.2: Product: Smart-UPS 750 FW:651.13.I USB FW:7.3 [ 4.205622] hid-generic 0003:051D:0002.0001: hidraw0: USB HID v1.10 Device [American Power Conversion Smart-UPS 750 FW:651 On the Rock64 board it works without problem. Here the output of the command # dmesg | grep Smart [ 2.175796] usb 3-1: Product: Smart-UPS 750 FW:651.13.I USB FW:7.3 [ 3.719981] hid-generic 0003:051D:0002.0001: hiddev0,hidraw0: USB HID v1.10 Device [American Power Conversion Smart-UPS 750 FW:651.13.I USB FW:7.3] on usb-ff5d0000.usb-1/input0 As you can see, on the Rock64 board there is hiddev0 hid-generic 0003:051D:0002.0001: hiddev0,hidraw0 and /dev/usb/hiddev0 exists. In the Odroid forum, I found only this post about CONFIG_USB_HIDDEV https://forum.odroid.com/viewtopic.php?f=93&t=28978 Thanks in advance. Link to comment Share on other sites More sharing options...
matteobp Posted September 30, 2018 Author Share Posted September 30, 2018 Same problem with latest Armbian Stretch. In both case I used Desktop version. Link to comment Share on other sites More sharing options...
Igor Posted September 30, 2018 Share Posted September 30, 2018 Bionic and Stretch share kernel. Try to compare working (rock64) with nonworking configuration ... perhaps some other config option is needed or there is a bug in Odroid USB stack. You can also switch between different kernels for XU4 if that helps ...Wrote on mobile Link to comment Share on other sites More sharing options...

How can I do it? On the Rock64 I have the ayufan Stretch image 0.6.44, kernel 4.4.132. I have to search in that kernel configuration. And I can try the Rock64 Armbian image to check if apcuspd works with it. Thanks Link to comment Share on other sites More sharing options...

So I can use the kernel configuration of the Rock64 board, I think this one linux-rockchip-next.config But it not simple, too many differences ... :-( Link to comment Share on other sites More sharing options...

matteobp Posted October 2, 2018 Author Share Posted October 2, 2018 I tried this image, and it works. https://forum.odroid.com/viewtopic.php?f=95&t=30888 [ 7.201747] usb 3-1.2.2: Product: Smart-UPS 750 FW:651.13.I USB FW:7.3 [ 7.321793] hid-generic 0003:051D:0002.0004: hiddev97,hidraw3: USB HID v1.10 Device [American Power Conversion Smart-UPS 750 FW:651.13.I USB FW:7.3] on usb-xhci-hcd.3.auto-1.2.2/input0 All posts I found about hiddev feature are based on old kernel, and refers to CONFIG_USB_DEVICEFS that is deprecated. Can I add a new post under Development section about enabling hiddev node in the kernel, or would it be considered a duplicate post? Thanks.

No need. It's a general kernel feature. Create a PR for kernel config changes when you figure out what exactly needs to be enabled - I don't know: https://docs.armbian.com/Process_Contribute/ Link to comment Share on other sites More sharing options...
matteobp Posted October 2, 2018 Author Share Posted October 2, 2018 Sure, I won't miss it. The problem is that enabling option CONFIG_USB_HIDDEV is not enough, something is still missing. I wanted to create a specific post in a general section because maybe someone else knows how to do it, but no problem. I'll try to compare the configuration kernel file of the other Ubuntu distribution, which I think is more similar to the Odroid XU4 Armbian configuration file than the Rock64 configuration file.

matteobp Posted October 4, 2018 Author Share Posted October 4, 2018 After several unsuccessful attempts, I decided to use the kernel configuration file of the "Ubuntu MATE 18.04 LTS" as it is, without any change, because in that distribution apcupsd works and the node /dev/usb/hiddev0 exists. Regretfully, it doesn't work on Armbian So my conclusion is that the problem is not just about the kernel, but there must be something else, and I have no idea what it might be. So I had to change and move on to the "Ubuntu Minimal 18.04 LTS" with XFCE Desktop Environment, and it works. https://wiki.odroid.com/odroid-xu4/os_images/linux/ubuntu_4.14/20180531 Link to comment Share on other sites More sharing options...
DarkHand Posted October 5, 2018 Share Posted October 5, 2018 I can also confirm that I've had this issue for some time. For me, the issue started around the time of the introduction of the 4.x series of kernels, on all distros for the XU4. When that change occurred, APCUPSD stopped working.

PatrikX Posted February 24, 2019 Share Posted February 24, 2019 Has anyone figured out what is preventing APCUPSD to work here? I am having the same issue on Odroid C2 using the latest Ubuntu 18.04 image. Everything works fine on Rock64. Link to comment Share on other sites More sharing options...
Sean Posted May 26, 2019 Share Posted May 26, 2019 @PatrikXThere was a driver missing related to USB, it has since been added/enabled. The latest kernel releases should support it, if not building an kernel package yourself will work, have done this myself and the APC UPS works just fine.

PatrikX Posted May 26, 2019 Share Posted May 26, 2019 Thank you for the update, Sean. I will give it a go. Link to comment Share on other sites More sharing options...
PatrikX Posted June 24, 2019 Share Posted June 24, 2019 I have tested it today and it still does not work. I get "Warning communications lost with UPS". It works on Rock64. Both Odroid C2 and Rock64 use latest Armbian Ubuntu 18.04. It looks like something is not quite right with the Odroid C2 image. Link to comment Share on other sites More sharing options...
