I have built the uhci_hcd driver into the kernel, and have selected usb_hid, usb_hiddev, usb_devicefs, and so on, and the software components seem to be in place. But something very strange is going on with my hardware. I cannot figure out why IRQ 5 is misbehaving and becoming disabled shortly after bootup. The uhci_hcd driver wants to use IRQ 5, but when it fails, communication with the UPS fails. I can still "see" the device. Unplugging it produces a disconnect message, and plugging it back in produces a recognition message with make and model of the UPS displayed, followed by a "failed to register" message. I have been relying on the very extensive manual accompanying the software I want to use, "apcupsd," but will give the web site a look that you mentioned. Joseph L. thinks it is a kernel configuration problem, but I'm damned if I can figure out what. I am running 2.6.11.11 on this Debian system, although the kernel is not a Debian package and I have configured and compiled it the old fashioned (Slackware) way! Some old dogs just cannot be taught new tricks. One other anomaly that makes me think Joseph might be correct: My bootup messages end with a complaint about an "unknown_bootoption" followed by an offset of some sort, but I have only specified the usual "speakup_synth=ltlk" option explicitly. If that is what it is complaining about, it is a benign message. But if it is something else, I cannot imagine what it might be.
