USB non-zero interface numbers
Most UPSes serve USB interactions on interface 0 which is default. Recent "composite devices" differ

For context, I think whatever support for non-zero interface numbers we have currently, is from #1044 (and possibly later commits in areas it touched upon - check by "git blame" or equivalent github UI). Which means it is relatively recent, was confirmed to "scratch one itch" and might be or not be incomplete for the general case. May I suggest you look at that PR (and possible differences of that codebase from current master), and try to craft, test and post a PR for a better solution? Something with a driver configuration option, debug messages to see there's more than one interface, probing for which one is HID, etc? :) Also note #1819 (and a few recent PRs before it) that touched on "common USB matching" codebase: if the solution is to be generic, it should probably land into these methods of libusb0, libusb1 and scan_usb files. |

I just bought a Vertive Edge 750VA, which seems to behave similarly to this with 1 configuration that has 2st interfaces, the first one tiny (27 bytes) and the second one large (662 bytes). Before i start patching code, is the usb_set_altinterface setting supposed to do this or is that something unrelated? |
|
Looking at https://github.com/search?q=repo%3Anetworkupstools%2Fnut%20usb_set_altinterface&type=code - it might help. At least, should be easy to verify by a configuration file tweak... |

The setting did not work: |

Thanks! In the meanwhile, I've got back to computers and re-checked the current source code (still matches the changes of PR #1044 in this area): it seems the Probably the easiest way forward would be to add a consistent (applicable to all libusb-based drivers) handling of config variables to tune The point you've brought up above about sizes of replies on different interface numbers (and for that matter - now wondering if there is a way to query how many interfaces a device has and/or get an array of specific numbers present in case there may be "holes", to iterate them properly - for one or both generations of libusb backend) sounds like another decent approach for auto-detection of the usable interface. Maybe in You offered to hack about this - would you care to post a PR to score those points? I'm a bit short on time, and lack a device with non-zero interface to test a fix, and in terms of community-building it is better to get more people well versed with the codebase :D |

Yes i can probably add those settings. My vacation starts after next week and i have nothing else planned. |
|
Thanks, that would be very welcome (and hopefully fun for you too) :) |

Hello There, What is also interesting, is NUT is reporting that the UPS is "On Battery" even though it isn't. To me, this feels related to this issue, but I am not certain. Any advice is greatly appreciated. |
|
No i never implemented anything. |
|
There was some discussion and maybe work in recent months. Anyhow, it would not be part of NUT v2.7.4 (released some 7 years ago). |
|
Fair point on the 7 year old build. I was able to get a temporary raspberry pi server hooked up running 2.8.1 on arch linux arm and had the same result as above. |
|
Hello, can you please check if #2331 helps regarding making these HID numbers tunable? Follow https://github.com/networkupstools/nut/wiki/Building-NUT-for-in%E2%80%90place-upgrades-or-non%E2%80%90disruptive-tests with this branch for the build: |

Thanks for the confirmation! Could you please check if it would also work without the (partial) changes from @x0ul that you've outlined above, just using the driver configuration options? Namely, I think the critical change was The effective removal of Finally, the I suppose the driver testing command (for code built from just my PR'ed branch) would look like this to run once, dump the data, and exit: (with normal driver service stopped, so the device is available for grabs). Also maybe let it run for a few data collection loops before exiting, with a larger |

Hi there, I have a UPS that seems to speak HID, but its configuration has two different interfaces under its (single) configuration. Interface 0 is small and has some vendor-specific junk, while interface 1 dumps a bunch of HID data and most of it fits into usages 0x84 and 0x85, resembling what is expected from a UPS. However, the usbhid driver in nut seems to be unable to communicate with interface 1, so it only sees the small junky data from interface 0 and doesn't think there's a UPS there.
Some data from usbhid-dump showing the two interfaces on my UPS.
Interface 0. Small, bad.
Interface 1. Big, good.
I pasted both those into
hidrd-convertand see the nice-looking 0x84, 0x85 usage pages (more here if you care to see).Some specifics now that I've introduced the problem and my interpretation. The UPS is a Liebert PST5 made by Virtiv and was bought on Amazon in the last month. The device's vid is 10af; pid is 0002. This sort of matches the Belkin HID driver, so I started from there trying to get it to work after adding a specific pid to match in ups.conf.
I hacked nut into talking to interface 1 and getting some decent data (perhaps incomplete, I stopped once I got comms working) with the following:
This hack I specifically made because according to the docs for
libusb_get_config_descriptor, the argumentusb_subdriver.hid_rep_indexrepresents the USB configuration, not the interface. In other code, namely the call tousb_claim_interfacehid_rep_indexis passed in as interface. This device only has one configuration, so I hard-coded the parameter to 0 here in order to make it work quickly for me. To me it seems likehid_rep_indexshould not be used for both configuration and interface, but I have not read enough nut code to really understand how it's used in depth.Evidence of communication after the hack above to talk to interface 1:
It'd be really cool to get this UPS supported, I bet there are other ones out there with the same little idiosyncrasy. I'm not sure how to make my hacky patch into a serious fix, but here it is in case you find it useful. Thanks for the nice software :)
