Steve, This APC bug is very alive on the APC forum boards. I have seen it here using XP. Many on Win7 and Vista are still seeing this also. APC has offered at least 2 patches to their(?) USB logic, but this problem continues. Many times the suggestion is to ditch the PCPE (personal edition) and use the Business edition. Perhaps, but the two versions of Business Edition I tried some years back did NOT like XP.
As I understand it, the APC Powerchute sw needs to disable the now default MS 'Hibernation' business and modify the default USB logic so that the PCPE app can communicate with the UPS. I get my UPS's to work by turning off the MS UPS Service in the Services window of Admin Tools. YMMV. The PowerChute sw (version 2.0 and 2.0.1) is buggy. The newer version 3.0 (and, now 3.0.0.1) appear to be a bit better, but my testing is only 2 months old.............. :) Duncan On 11/11/2011 08:52, Steve Tomporowski wrote:
Time to ask for help. I've been around and around this a few times. Problem: I bought a 2nd APC Back-UPS (good thing I did, with all the power outages here in CT), for the 2nd computer. P55 Gigabyte MB, 650 Watt Power supply. APC provides power monitoring software and funky RJ45 to USB cable from the UPS to the PC for communications. Roughly 90% of the time, the PC will not recognize the UPS. APC's main solution to this is to unplug and replug the cable unit the unit is recognized. As a baseline, I've had several USB mice, a couple of USB keyboards, a couple of Printers, a couple of USB hard drives and one ancient Canon scanner hooked up to this system and never have had something not be recognized. Except this UPS. If I plug and unplug the cable enough times, it will be recognized. However, I have to do this at each and every time I power on or restart. Yes, legacy USB support is on in BIOS. I cannot find 'Advanced Power Management' in BIOS to turn it off. Unless someone knows of a real solution to this problem, I'm going to ditch the cable and the software and forget it. Anyone familiar with this problem? Thanks...Steve
