hmm... this sounds familiar. You're not related to GitHub issue #674 (https://github.com/networkupstools/nut/issues/674), right? > Observing the usb chatter in wireshark showed that the UPSmart program > received and sent an URB_INTERRUPT to 0x81 EP. This was happening in a > pattern of receive/send URB_INTERRUPT followed by 5 GET_DESCRIPTOR > request/respond. This was the same thing I got to, the last time I looked into that (after #307, there have been some other topics on the lists or on GitHub, I can't remember exactly now). > The UPS is cheap and cheerful, details can be found here > https://www.jaycar.com.au/650va-390w-line-interactive-ups-with-lcd-and-usb/p/MP5205 > The badge on the front says 'DIGITECH Computer', model MP5205 > > I opened the case up and removed the comms board, but there's nothing much to > go on.

Also, if you're open to (building and) testing what I throw at you, I can try to implement something to mimic what's in #307 / #674. _______________________________________________ Nut-upsuser mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
