Hi Yesterday I had 2 different APC UPS using USB get in power off recoverable state.
dmesg said: 7705944.352083] usb 2-1: new low speed USB device using uhci_hcd and address 2 [7705944.477061] usb 2-1: device descriptor read/64, error -71 [7705944.709035] usb 2-1: device descriptor read/64, error -71 [7705944.925071] usb 2-1: new low speed USB device using uhci_hcd and address 3 [7705945.048048] usb 2-1: device descriptor read/64, error -71 [7705945.277069] usb 2-1: device descriptor read/64, error -71 [7705945.496067] usb 2-1: new low speed USB device using uhci_hcd and address 4 [7705945.904052] usb 2-1: device not accepting address 4, error -71 [7705946.016058] usb 2-1: new low speed USB device using uhci_hcd and address 5 [7705946.434625] usb 2-1: device not accepting address 5, error -71 [7705946.434666] hub 2-0:1.0: unable to enumerate USB device on port 1 [7706009.452060] usb 2-1: new low speed USB device using uhci_hcd and address 6 [7706009.580040] usb 2-1: device descriptor read/64, error -71 [7706009.808044] usb 2-1: device descriptor read/64, error -71 [7706010.025073] usb 2-1: new low speed USB device using uhci_hcd and address 7 [7706010.148048] usb 2-1: device descriptor read/64, error -71 [7706010.377126] usb 2-1: device descriptor read/64, error -71 [7706010.593072] usb 2-1: new low speed USB device using uhci_hcd and address 8 [7706011.004481] usb 2-1: device not accepting address 8, error -71 [7706011.117044] usb 2-1: new low speed USB device using uhci_hcd and address 9 [7706011.529059] usb 2-1: device not accepting address 9, error -71 [7706011.529104] hub 2-0:1.0: unable to enumerate USB device on port 1 The machine is a guruplug server plus, running debian lenny on armtel. Linux dkplugbab9 2.6.32-00007-g56678ec #1 PREEMPT Mon Feb 8 03:49:55 PST 2010 armv5tel GNU/Linux I have hand installed Network UPS Tools upsstats 2.4.3 from source. ups.conf: [apc1500] driver = usbhid-ups port = auto serial=AS0535132782 # powers switches and routers [Smart-UPS_3000] driver = usbhid-ups port = auto serial=JS1030003421 [R3000XR] port = /dev/ttyUSB0 driver = bcmxcp The R3000XR did work, but neither apc1500 nor Smart-UPS_3000. I tried restarting nut, I tried in other linux servers (just plugging in and seeing dmesg). Nothing helped. So I scheduled downtime and powered off the UPses. That did help, and since that nut has been able to monitor the UPSes.
