Making extension for NUT with usb support. Problems with permissions (udev)

[rabtux]

Hi!
I am making a tiny core extension for Network UPS Tools (NUT) with support for usbhid-ups driver (connecting to ups over usb).
(www.networkupstools.org)

I have compiled it for tiny core, but I have some permission problems.
I have installed it from source and configured it to run as user=ups and group=nut (./configure --with-user=ups --with-group=nut)
I have also made this user on the tiny core machine.

If I try to start, it won't work:

Code: [Select]

root@Dalen:/usr/local/ups/bin/upsdrvctl start eaton
I get this error message:

Network UPS Tools - UPS driver controller 2.6.4
Network UPS Tools - Generic HID driver 0.37 (2.6.4)
USB communication driver 0.31
No matching HID UPS found
Driver failed to start (exit status=1)
If I run the driver itself as user=ups I get this error

Code: [Select]

root@Dalen:/home/tc# /usr/local/ups/bin/usbhid-ups -u ups -DD -a eaton
Network UPS Tools - Generic HID driver 0.37 (2.6.4)

root@Dalen:/home/tc#
If I run as root the the driver connect works and connect to the ups.


I asked on the mailing list for Network UPS tools and I learned that access rights is addressed on Linux through udev. I was told that running

Code: [Select]

$ udevadm trigger --subsystem-match=usb --action=change and unplug/replug usb cable should solve the problem, but with no luck.
I have also tried running

Code: [Select]

udevadm control --reload-rules with no luck.

For just to check that the program is working and its a permission problem I tried this:
chmod 0777 directly on usb bus that the ups is connected to the root@Dalen:/usr/local/ups/bin/upsdrvctl start eaton will start and I can start the upsd deamon and everything is working


Does anyone have any ideas whats wrong? Is it possible that something is wrong with the udev rule or maybe the rule is not loaded?


the udev rule is placed in:

Code: [Select]

You could try configuring with user=tc and group=staff?

[rabtux]

I tried configuring with user=tc and group er staff and it works.

but this is because of all the usb bus is owned by root:staff by default.

it has nothing to do with udev. I deleted the udev rule and its still working...
