Hello, On my 8.0-RELEASE machine running GENERIC this happened this afternoon: Mar 28 17:48:13 yomi apcupsd[969]: UPS Self Test switch to battery. Mar 28 17:48:17 yomi kernel: ugen0.2: <American Power Conversion> at usbus0 (disconnected) Mar 28 17:48:18 yomi kernel: usb_alloc_device:1586: set address 2 failed (USB_ERR_STALLED, ignored) Mar 28 17:48:18 yomi kernel: usb_alloc_device:1624: getting device descriptor at addr 2 failed, USB_ERR_STALLED! Mar 28 17:48:19 yomi kernel: usbd_req_re_enumerate:1539: addr=2, set address failed! (USB_ERR_STALLED, ignored) Mar 28 17:48:19 yomi kernel: usbd_req_re_enumerate:1553: getting device descriptor at addr 2 failed, USB_ERR_STALLED! Mar 28 17:48:20 yomi kernel: usbd_req_re_enumerate:1539: addr=2, set address failed! (USB_ERR_STALLED, ignored) Mar 28 17:48:20 yomi kernel: usbd_req_re_enumerate:1553: getting device descriptor at addr 2 failed, USB_ERR_STALLED! Mar 28 17:48:20 yomi kernel: ugen0.2: <(null)> at usbus0 (disconnected) Mar 28 17:48:20 yomi kernel: uhub_reattach_port:435: could not allocate new device! Mar 28 17:48:27 yomi apcupsd[969]: Communications with UPS lost. Unplugging the UPS and replugging it doesn't seem to help, even in a different port. My UPS is a Smart-UPS 750 and my apcupsd is "3.14.5 (10 January 2009) freebsd". ugen0.1: <UHCI root HUB VIA> at usbus0, cfg=255 md=HOST spd=FULL (12Mbps) pwr=ON ugen1.1: <UHCI root HUB VIA> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON dev.usbus.0.%desc: VIA 83C572 USB controller dev.usbus.1.%desc: VIA 83C572 USB controller I'm happy to provide more info if someone sufficiently clueful can tell me where to look :) Thanks, James
