While in a few minutes I got working a Chinese serial-connection UPS, I am experiencing diffulties with APC via USB as STANDALONE (kernel 2.6.15-1).
With ref to Sibbald manual, for APC CS 500 as an example (while I have to configure also RS 1500), and with my aim of simply having done at poweroff/battery low: #Ctrl C (to kill mpqc231 computation; there is no X system) # shutdown -h now (to close Debian) Device and driver are detected: $cat /proc/bus/usb/devices T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 3 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 2.06 S: Manufacturer=Linux 2.6.15-1-k7 ohci_hcd S: Product=OHCI Host Controller S: SerialNumber=0000:00:02.2 C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)
