This is what I was referring to (from the belkin-hid log): 1.325782 Report[buf]: (5 bytes) => 05 53 00 48 00 1.325799 Path: UPS.PowerSummary.ConfigVoltage, Type: Feature, ReportID: 0x05, Offset: 16, Size: 16, Value: 0 1.325814 ConfigVoltage = 0 -> assuming correction factor = 1e+08 You may need to bump the debug level to 5 to see the full exponent processing (cf get_unit_expo() in libhid.c). Please gzip the log - it will be big. > However.

I would prefer not to move things around too much, unless we can get people to test the other models. I realize it is annoying that the subdriver names do not match the brands, but the idea is that the matching happens automatically. > (2) i don't understand how the driver selection is done ? if i just add the > vendorid/productid to the liebert_usb_device_table, the lookup seems to stop > in the belkin driver (perhaps because belkin_claim got "possibly supported" > and that the "productid" value is present ?). > How do you suggest to implement the addition of this device ? > (for my tests, i commented the belkin lookup entry to force the usage of the > liebert one). Right, in usbhid-ups.c, the liebert_subdriver entry is after the belkin_subdriver. > (3) in the hid report, we have several items with the same name (see attached > lsusb dump). > How it is handled by the lookup table ? Is there any indexing possible ? I will have more time to look at this later, but at a quick glance, I did not see what you were referring to (the lsusb dump, while comprehensive, is hard to parse). Bear in mind that many vendors duplicate Input and Feature HID elements. > (4) would it be usefull to add missing items to the driver's hid to nu lookup > table (even in the the unmapped part) ? Sure, although the unmapped entries are just for debugging - we will want to eventually rename them to official NUT names, or comment them out again before checking the driver in to version control. > Do you recommend me to work on the liebert or on the belkin file ? Probably belkin-hid. > Thanks for your help.
