Hey, was wondering if I could get a quick sanity check. We have a SmartUPS 1500 RM2U which we have connected to a box via USB. It seems like every 40-45 seconds it becomes disconnected and reconnected. Though this only happens when we have NUT enabled, otherwise it's fine. When it is disconnecting and reconnecting running lsusb doesn't show it disconnecting. After having it sit like that for a day NUT was unable to connect to the driver.
So I was wondering does NUT do anything which would cause the USB to disconnect? I didn't think so and I couldn't find anything yet it's quite possible I missed it. I've tested this with CentOS 6.5 and Fedora 20. With CentOS we were using nut-client-2.6.5-2.el16.x86_64 and nut-2.6.5-2.el6.x86_64. With Fedora we were using nut-2.7.2-1.fc20.x86_64 and nut-client-2.7.2-1.fc20.x86_64. Here is what the logs look like - CentOS - ite TRIPP LITE SMART1500RM2UN ] on usb-0000:00:1d.2-1/input0 Sep 19 17:49:41 localhost kernel: usb 8-1: USB disconnect, device number 118 Sep 19 17:49:41 localhost kernel: usb 8-1: new low speed USB device number 119 using uhci_hcd Sep 19 17:49:41 localhost kernel: usb 8-1: New USB device found, idVendor=09ae, idProduct=3015 Sep 19 17:49:41 localhost kernel: usb 8-1: New USB device strings: Mfr=2, Product=3, SerialNumber=4 Sep 19 17:49:41 localhost kernel: usb 8-1: Product: TRIPP LITE SMART1500RM2UN Sep 19 17:49:41 localhost kernel: usb 8-1: Manufacturer: Tripp Lite Sep 19 17:49:41 localhost kernel: usb 8-1: SerialNumber: 2424AY0SM882300229 Sep 19 17:49:41 localhost kernel: usb 8-1: configuration #1 chosen from 1 choice Sep 19 17:49:42 localhost kernel: generic-usb 0003:09AE:3015.0171: hiddev96,hidraw2: USB HID v1.10 Device [Tripp Lite TRIPP LITE SMART1500RM2UN ] on usb-0000:00:1d.2-1/input0 Sep 19 17:50:26 localhost kernel: usb 8-1: USB disconnect, device number 119 Sep 19 17:50:26 localhost kernel: usb 8-1: new low speed USB device number 120 using uhci_hcd Sep 19 17:50:26 localhost kernel: usb 8-1: New USB device found, idVendor=09ae, idProduct=3015 Sep 19 17:50:26 localhost kernel: usb 8-1: New USB device strings: Mfr=2, Product=3, SerialNumber=4 Sep 19 17:50:26 localhost kernel: usb 8-1: Product: TRIPP LITE SMART1500RM2UN Sep 19 17:50:26 localhost kernel: usb 8-1: Manufacturer: Tripp Lite Sep 19 17:50:26 localhost kernel: usb 8-1: SerialNumber: 2424AY0SM882300229 Sep 19 17:50:26 localhost kernel: usb 8-1: configuration #1 chosen from 1 choice Sep 19 17:50:27 localhost kernel: generic-usb 0003:09AE:3015.0172: hiddev96,hidraw2: USB HID v1.10 Device [Tripp Lite TRIPP LITE SMART1500RM2UN ] on usb-0000:00:1d.2-1/input0 Fedora - Sep 19 19:46:19 nemo kernel: usb 8-1: USB disconnect, device number 6 Sep 19 19:46:19 nemo usbhid-ups[1595]: libusb_get_interrupt: No such device or address Sep 19 19:46:19 nemo usbhid-ups[1595]: libusb_get_report: No such device or address Sep 19 19:46:19 nemo kernel: usb 8-1: new low-speed USB device number 7 using uhci_hcd Sep 19 19:46:20 nemo kernel: usb 8-1: New USB device found, idVendor=09ae, idProduct=3015 Sep 19 19:46:20 nemo kernel: usb 8-1: New USB device strings: Mfr=2, Product=3, SerialNumber=4 Sep 19 19:46:20 nemo kernel: usb 8-1: Product: TRIPP LITE SMART1500RM2UN Sep 19 19:46:20 nemo kernel: usb 8-1: Manufacturer: Tripp Lite Sep 19 19:46:20 nemo kernel: usb 8-1: SerialNumber: 2424AY0SM882300229 Sep 19 19:46:20 nemo kernel: hid-generic 0003:09AE:3015.0007: hiddev0,hidraw2: USB HID v1.10 Device [Tripp Lite TRIPP LITE SMART1500RM2UN ] on usb-0000:00:1d.2-1/input0 Sep 19 19:46:20 nemo mtp-probe[1689]: checking bus 8, device 7: "/sys/devices/pci0000:00/0000:00:1d.2/usb8/8-1" Sep 19 19:46:20 nemo mtp-probe[1689]: bus: 8, device: 7 was not an MTP device Sep 19 19:46:49 nemo kernel: usb 8-1: USB disconnect, device number 7 Sep 19 19:46:49 nemo kernel: usb 8-1: new low-speed USB device number 8 using uhci_hcd Sep 19 19:46:49 nemo usbhid-ups[1595]: libusb_get_interrupt: No such device or address Sep 19 19:46:49 nemo usbhid-ups[1595]: libusb_get_report: No such device or address Sep 19 19:46:49 nemo kernel: usb 8-1: New USB device found, idVendor=09ae, idProduct=3015 Sep 19 19:46:49 nemo kernel: usb 8-1: New USB device strings: Mfr=2, Product=3, SerialNumber=4 Sep 19 19:46:49 nemo kernel: usb 8-1: Product: TRIPP LITE SMART1500RM2UN Sep 19 19:46:49 nemo kernel: usb 8-1: Manufacturer: Tripp Lite Sep 19 19:46:49 nemo kernel: usb 8-1: SerialNumber: 2424AY0SM882300229 Sep 19 19:46:50 nemo kernel: hid-generic 0003:09AE:3015.0008: hiddev0,hidraw2: USB HID v1.10 Device [Tripp Lite TRIPP LITE SMART1500RM2UN ] on usb-0000:00:1d.2-1/input0 Sep 19 19:46:50 nemo mtp-probe[1699]: checking bus 8, device 8: "/sys/devices/pci0000:00/0000:00:1d.2/usb8/8-1" Sep 19 19:46:50 nemo mtp-probe[1699]: bus: 8, device: 8 was not an MTP device These messages just repeat indefinitely.
