I know about this problem. But I didn't know about auto keyword, which breaks device permissins in the init script. See the bug 156614 comment #1. We need udev integration for fixing of this problem.

You have to wait for it to appear and it's a different event. Only HAL works around this and until we get the next version of raw usb access, Greg is working on, we have to work around this. > Details: > > Not all devices in the list are HID. > > Owner must not be dependend on user logged in (it must be "upsd" in all > cases). It's impossible with udev, without matching on vendor/product and create custom device nodes with that group. The only instance on the system knowing that it's a UPS is HAL, but HAL does not change device permissions. So there is currently no way besides matching on vendor/product and listing all known devices. Kay Now setting permissions for all known USB "auto" devices in the init script.

/etc/init.d/upsd
New init script attached. Could you test it, please?
With my (newhidups) it does exactly what it should do (sets permissions for device you proposed), but the newhidups seems not to work properly here.
I even tried to set owner of /dev/bus/usb/004/001 (which is bad, because the permission is not returned back after unplugging and replugging), but it does not help, too.

Accesses to other USB devices returned EACCES, exactly as expected.
I just tried the new init.d script. I'm getting the following error: root@gq-serv:/etc/init.d>./upsd start ./upsd: invalid /dev/bus/usb/002/008 in /etc/ups/ups.conf failed The script identifies the correct USB device. lsusb Bus 005 Device 001: ID 0000:0000 Bus 004 Device 002: ID 04b8:0110 Seiko Epson Corp.

Just tried the new init.d script. Unfortunately it failed because you have changed the way the usb bus numbers are created. Unfortunately I do not understand the syntax of the way you create the port in the following line otherwise I would try and fix it for you. PORT=$(LANG=C LC_ALL=C lsusb | grep '\(0463:ffff\|0463:0001\|051d:0002\|0592:0002\|09ae:0001\)' | sed 's:^:/dev/bus/usb/:;s/Bus //;s/ Device /\//;s/: .*//') The above resolves to /dev/bus/usb/002/008 but the path is incorrect as the file is as below ls -l /dev/bus/usb/2 lrwxrwxrwx 1 root root 18 2006-04-20 16:44 1 -> ../../../usbdev2.1 lrwxrwxrwx 1 root root 18 2006-04-27 06:04 8 -> ../../../usbdev2.8 So the actual link is now /dev/bus/usb/2/8 The syntax is simple: Remove all standard strings from lsusb and keep only reported numbers. On my system, /dev/bus and lsusb report exactly the same, including the leading zeroes and the node was /dev/bus/usb/005/013. Please note, that on my SuSE Linux 10.1 RC1 x86_64, usbdevfs is not mounted by default. To Kay Sievers: Can you advice a method, which will return exact device associated with defined ID, which works on any hardware? Ick, that's not a default setup. There are no links in /dev/bus/usb, there are real nodes. Stanislav, what do you mean with "ID" and "association" and "device"? I have a list of idVendor:idProduct of known USB UPS device. When starting the upsd, I need to set owner of /dev/bus/usb/x/y nodes created for one of these devices. On my machine, there are files with file/dir names with leadind zeroes, on Graham Smith's machine there are symlinks with file/names without leading zeroes, but lsusb still reports them with leading zeroes. His setup is broken, it's not a correct 10.1 installation. We don't do symlinks here. We always have real nodes with leading zeros. Oh, why is the bug against 10.1 when the user mentions a 10.0 system? It seems, that the solution in 10.1 is not portable to 10.0. Please retry in 10.1 and newer and reopen, if the bug appears again. WONTFIX for 10.0 |
I have a Powerware 3105 UPS and am trying to get nut to work with it. The UPS communicates via a USB port using the bcmxcp_usb driver. I am using SuSE 10.0 which comes with nut 2.02 which does not support this UPS so I downloaded nut-2.0.3-13.src.rpm from the 10.1 factory depository and compiled it without any problems. There is a problem with the port configuration and permissions relating to the USB Bus arrising from the startup script /etc/init.d/upsd. From lsusb I get the following output Bus 002 Device 006: ID 0592:0002 Powerware Corp. If I change the owner of /proc/bus/usb/002/006 to upsd:root I can get the bcmxcp_usb driver to load. From the man pages on bcmxcp_usb driver it recommends /etc/ups/ups.conf be set as follows [pw3105] driver = bcmxcp_usb port = auto Now in the startup script /etc/init.d/upsd if you assign 'auto' to the port setting the script will fail as it requires a physical port to be entered so that the program can change ownership of the port. I believe the script will only work with serial ports. USB ports appear to be configured differently.
