installing apcupsd! where is usb device??

sueisfine · 05-06-2004, 10:08 AM

i got myself an APS Backups, which connects PC through USB. i installed apcupsd for controlling my UPS. i ran into problem when i wanted to configure the program.

Code:

#   NOTE!!! for USB devices, please use a form indicated below
#      including the [0-15] as written!
#
# Driver   Device                    Description
# dumb     /dev/tty**                Serial character device
# apcsmart /dev/tty**                Serial character device
# usb      /dev/usb/hiddev[0-15]     On most systems
# net      hostname:port             Network link to a master apcupsd
#                                    through NIS
DEVICE /dev/ttyS0 # default

but in /dev/usb there is no hiddev's

Code:

bash-2.05b# ls /dev/usb/
ez0   ez15  ez8   lp13  lp6      mouse11  mouse4  scanner0   scanner15  scanner8
ez1   ez2   ez9   lp14  lp7      mouse12  mouse5  scanner1   scanner2   scanner9
ez10  ez3   lp0   lp15  lp8      mouse13  mouse6  scanner10  scanner3
ez11  ez4   lp1   lp2   lp9      mouse14  mouse7  scanner11  scanner4
ez12  ez5   lp10  lp3   mouse0   mouse15  mouse8  scanner12  scanner5
ez13  ez6   lp11  lp4   mouse1   mouse2   mouse9  scanner13  scanner6
ez14  ez7   lp12  lp5   mouse10  mouse3   rio500  scanner14  scanner7

i use hotplug to detect my usb devices.

Code:

bash-2.05b# lsusb

E:  Ad=81(I) Atr=03(Int.) MxPS=   6 Ivl=100ms

where i can find the propriate device to use it in conf file?

Use dmesg to see where the device was added. I don't know if that's any help.

Hi,

I am having the same problem. I think I just found the solution, but haven't yet tried it. If you read through the documentation of kernel 2.6.6 (the kernel I am having this problem with), look at the file /Documentation/usb/hiddev. This document states:

The hiddev interface is a char interface using the normal USB major,
with the minor numbers starting at 96 and finishing at 111. Therefore,
you need the following commands:
mknod /dev/usb/hiddev0 c 180 96
mknod /dev/usb/hiddev1 c 180 97
mknod /dev/usb/hiddev2 c 180 98
mknod /dev/usb/hiddev3 c 180 99
mknod /dev/usb/hiddev4 c 180 100
mknod /dev/usb/hiddev5 c 180 101
mknod /dev/usb/hiddev6 c 180 102
mknod /dev/usb/hiddev7 c 180 103
mknod /dev/usb/hiddev8 c 180 104
mknod /dev/usb/hiddev9 c 180 105
mknod /dev/usb/hiddev10 c 180 106
mknod /dev/usb/hiddev11 c 180 107
mknod /dev/usb/hiddev12 c 180 108
mknod /dev/usb/hiddev13 c 180 109
mknod /dev/usb/hiddev14 c 180 110
mknod /dev/usb/hiddev15 c 180 111

Maybe you can check this document (e.g. in http://www.kernel.org/pub/linux/kern...x-2.6.6.tar.gz)

Hope this helps (if it works I'll post another post here)

thanks man! i have 2.6.6 too. i don't know when i have time to test it, but i let know, if i achieve anything.

is this 96-111 range optional? what is those numbers all about?

...

but anyways. it works! i just did the real power-failure test successfully!
