It seems that the new home for usb.ids is in https://usb- ids.gowdy.us/index.html (from the same mainainer).

IIRC debian has a tools to merge different ids files. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/780356 Title: upgrade-usbids not working any more -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
