Accessing a USB device

[Charles Hallenbeck]

Well I'll be dipped!

Suddenly it's working. After writing about my woes I thought I'd try it 
one more time, and at least generate that "failure to register" error. 
When I unplugged the USB cable and plugged it in again, I got this:

usb 2-1: USB disconnect, address 3

usb 2-1: new low speed USB device using ohci_hcd and address 4
hiddev96: USB HID v1.10 Device [APC Back-UPS ES 350 FW:800.e5.D USB 
FW:e5] on usb-0000:00:0b.0-1
*** There used to be an error message appearing right here, but this 
time none. ***

So then I ran the test program, which said I might still have a problem, 
but I went ahead anyway and ran the monitoring daemon, which ran without 
complaint. Next, I ran the "access" program to display the status of my 
UPS, and here is my proud outcome:

*** Theoretically I know what all that stuff means. That is, I know 
where to look it up! <smile> ***


Now for my obsessive self flagellation: I don't know why the damn thing 
did not work before, and I don['t know why it is working now. But this 
is looking pretty good to me right now. A prolonged power outage will 
shut my system down gracefully, and will also turn off the UPS itself. I 
will have to do some more configuring to get it to restart unattended 
when power is restored, but the book says I can do that if I want to.

Pretty soon this computer will not need me at all, for anything, and I 
will be FREE!
