Good Morning: I'm trying to get my UPS to work with my Linux box. I'm running Red Hat 9.0 with all of the latest updates. I have an APC SmartUPS 1000XL, and I believe that it is being seen correctly on the bus. A quick look at /proc/bus/usb/devices has the last entry showing this: T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=1.5 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=051d ProdID=0002 Rev= 0.06 S: Manufacturer=American Power Conversion S: Product=Smart-UPS 1000 XL FW:631.3.D USB FW:1.5 S: SerialNumber=AS0315130454 C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr= 30mA I: If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=(none) E: Ad=81(I) Atr=03(Int.) MxPS= 6 Ivl=100ms If I read it correctly, the device number is 2. Now, reading through the documentation found at www.linux-usb.org, it didn't specifically state what driver to try for a UPS. Looking at /proc/bus/usb/drivers, I got this: drivers usbdevfs hub 96-111: hiddev hid Since it appeared that the device was being seen by the system, I tried to properly configure upsmon to see the device, and have the ups service properly start. However, when /etc/rc.d/init.d/ups starts, I'm presented with this: Starting hidups: Network UPS Tools: HID UPS driver 0.11 (1.2.0) Warning: This is an experimental driver. Some features may not function correctly. /dev/ttyS0 is not a UPS Starting upsd: [OK] Starting UPS monitor (master): Network UPS Tools upsmon 1.2.0 Fatal error: insufficient power configured! Sum of power values........: 0 Minimum value (MINSUPPLIES): 1 Edit your upsmon.conf and change the values. upsmon.conf: invalid directive MONITOR UPS@xxxxxxxxx 1 master Using power down flag file /etc/killpower Here is a copy of my configuration files: *** /etc/ups/ups.conf *** [UPS] driver = hidups port = /dev/usb/hiddev2 *** End /etc/ups/ups.conf *** *** upsmon.conf *** It is the default file included. The only line I added was: MONITOR UPS@xxxxxxxxx 1 master *** End /etc/ups/upsmon.conf *** Now, I'm probably doing something really dumb, or have my configuration wrong. Anyone have some experience that might be able to point me in the right direction? Thanks. - Michael
