Hello, I forgot nut since more than a year because a lot of job with other application My server nut failed since severals months We had 3 electric failure so I must install a new server nut I work with ubuntu 10.04.4 (64bits) / I installed nut 2.4.3 with deposits I have a MGE Pulsar evolution 2200 connected on usb last week when I began my tests all was ok (communication etc etc ..) Yesterday, I tried a simulate electric failure and now, my ups is not recognized on usb the lsusb command doesn't find anymore my ups when i unplug/plug it i have these errors** onduleur kernel: [ 279.070014] usb 4-1: new low speed USB device using uhci_hcd and address 7 onduleur kernel: [ 279.200015] usb 4-1: device descriptor read/64, error -71 onduleur kernel: [ 279.432511] usb 4-1: device descriptor read/64, error -71 onduleur kernel: [ 279.660013] usb 4-1: new low speed USB device using uhci_hcd and address 8 onduleur kernel: [ 279.790014] usb 4-1: device descriptor read/64, error -71 onduleur kernel: [ 280.030013] usb 4-1: device descriptor read/64, error -71 onduleur kernel: [ 280.260012] usb 4-1: new low speed USB device using uhci_hcd and address 9 onduleur kernel: [ 280.680011] usb 4-1: device not accepting address 9, error -71 onduleur kernel: [ 280.800013] usb 4-1: new low speed USB device using uhci_hcd and address 10 onduleur kernel: [ 281.220010] usb 4-1: device not accepting address 10, error -71 onduleur kernel: [ 281.220325] hub 4-0:1.0: unable to enumerate USB device on port 1 **I had this last year on my old server but i never found how to resolve When nut service start i normally have this in syslog Can't connect to UPS [OND1] (usbhid-ups-OND1): No such file or directory What can I do ? Thanks a lot for your help
hello, failing to run my UPS with USB, I tried with rs232 I used mge-shut driver on ttyS0 but it doesn't work /lib/nut# ./mge-shut -DDD -a ond3 Network UPS Tools - Eaton / SHUT driver 0.69 (2.4.3) 0.000000 debug level is '3' 0.000759 entering upsdrv_initups() 0.000904 entering setline(1) 0.000925 entering shut_ups_start() 0.000941 sent: (1 bytes) => 16 1.001987 sent: (1 bytes) => 16 2.003020 sent: (1 bytes) => 16 3.004058 sent: (1 bytes) => 16 4.005085 No communication with UPS Have you got any idea ?

I would suspect some EMI issue. is it an external USB hub? are there other devices on the same bus than the UPS? what is the result of "grep EMI /var/log/messages"? cheers, Arnaud -- Linux / Unix Expert R&D - Eaton - http://powerquality.eaton.com Network UPS Tools (NUT) Project Leader - http://www.networkupstools.org/ Debian Developer - http://www.debian.org Free Software Developer - http://arnaud.quette.free.fr/
