Hi, Sometime ago [ June 2018 ] I posted a message about getting trying to get NUT to work with a Power Shield Defender 1200VA UPS. This model appears in the HCL at https://networkupstools.org/stable-hcl.html That UPS reported the following when queried using 'lsusb' on an iMac running macOS [ 10.15 ] Bus 001 Device 008: ID 0665:5161 Cypress Semiconductor USB to Serial Device Descriptor:

...stem from the fact that the Report Descriptor is much larger than any other UPS I've seen (61939 bytes). Here is the quick fix that I put in libusb.c after getting the HID descriptor, and before getting the Report descriptor, which seems to work okay: if (desc->wDescriptorLength > 4096) { desc->wDescriptorLength = 4096; } I'm sure there is a better way to handle this. I'm just wondering if this is okay to do, and if anyone had a better way to fix it. Thanks!

...the instability of the old model. Further down in the lsusb output should be some information about the HID interface. A good distinguishing factor between Power Device Class (PDC) HID devices and simpler serial-over-HID devices is the size of the HID descriptor. What does the newer model show for wDescriptorLength?

Hi, I have an UPS with only the marking D1000 on it and it came with Junda-Tech's UpsMate. Its USB id is 3344:0025, which is apparently a microprocessor. I've could get some of the HID interactions as described on the website, but there are some outstanding. Junda-Tech does not respond to any queries. Does anybody else have the same or a similar UPS with more information? What is the

Is that with both UPSes on same machine? A quick guess would be that insufficient data points to identify the device are configured (vendorid, productid, serial...) in ups.conf, so both drivers connect to the first match. I'd expect them to conflict and one would die or both loop reconnecting, if both are running at once, though. Also, which NUT version? Custom build from GitHub or an
