i have a similar situation with three ups's also. two of them are the same, yet on different bus's and then a third on the same bus. the third gives a serial number and the other two do not. i'm trying to match the serial number to try and get around the driver seeing them as only one and then getting the errors in the logs and the data stale readings. could you provide what the preferred method is for putting the serial number in ups.conf? lsusb -v - Bus 003 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x051d American Power Conversion idProduct 0x0002 Uninterruptible Power Supply bcdDevice 1.06 iManufacturer 3 American Power Conversion iProduct 1 Back-UPS RS 1500 FW:8.g9 .D USB FW:g9 iSerial 2 JB0531034179 ups.conf - [sam] driver = usbhid-ups port = auto serial = 2 JB0531034179 # upsdrvctl start sam Network UPS Tools - UPS driver controller 2.4.3 Network UPS Tools - Generic HID driver 0.34 (2.4.3) USB communication driver 0.31 No matching HID UPS found Driver failed to start (exit status=1) version - 2.4.3-1ubuntu5 thank you chad _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
