...I haven't checked cabling, but AFAIK its still plugged in, but not sure if its usb or serial cabling. I'll check that once I get both eyes open simultaneously and report back. Found the cable, a D type usb, unplugged it and replugged it, and it appears now to be /dev/usb/hiddev3. dmesg, ever so helpful, and lsusb equally helpful, do not tell what the /dev/usbdevice is assigned to the newly discovered plugin. dmesg just reports: [136319.530160] usb 1-10: USB disconnect, device number 2 [136322.641716] usb 1-10: new low-speed USB device number 3 using ohci-pci [136322.92...

The Linux box only has a serial UPS attache...

Greetings; Its unk because whats plugged in seems to be blocking the rear name plate. About all I can recall is that its big, 3 battery unit, rated somewhere north ob 1250 VA.
