Gnomad2 with resmgr

Kashra · 10-09-2005, 03:11 PM

I'm using SuSE 10 and have installed libnjb and gnomad2 using the source RPMS. Gnomad2 works fine when run as root, but I can't get it to work as a user (usb_set_configuration: Operation not permitted).

It seems, from searching archives, that this is a device permissions problem. I've checked the presence of the /etc/hotplug/usb/ files (nomadjukebox and nomad.usermap) and they seem fine. In the nomadjukebox script, there's a region where it checks of I have resmgr present (which I do) and executes the following:

Code:

# Special quirk for SuSE systems using "resmgr"
# (see http://rechner.lst.de/~okir/resmgr/)
if [ -f /sbin/resmgr ]
then
    /sbin/resmgr "${ACTION}" "${DEVICE}" desktop usb
    exit 0
fi

Is there some way I can check if this is working properly? My understanding from reading the resmgr man pages is that this tool is suppoed to allow users access to these devices, even when they're hotplugged.

As root, if I use "resmgr list" I get a report of no devices found, even though I know the device is connected and accessible using gnomad under root.

An update:

Haven't solved my problem yet, but I've realized that most distros have switched off of hotplug to the new udev system. This probably means that the files in /etc/hotplug/usb aren't doing a damn thing.

Anyone know if there's a udev rules file that accomplishes the same thing as these scripts, or if this even sounds like a reasonable thing to research?

BUMP

Similar problem, similar question. Any convenient way to do this without root?

My current (and not satisfying) solution is, as suggested by Oliver Eichler from the libnjb mailing list:

Edit /etc/fstab's entry for the usbfs system to include 'devmode=0666'. Then add a line somewhere in your startup scripts to umount / mount the usbfs system at boot time. (I'm not sure why this entry doesn't make a difference if you don't umount/mount).

This seems to have implications for the entire usb system, not just for libnjb. But I haven't noticed any problems yet.

Appreciate the response, and thanks for the proposed solution, I think I'll leave it as it is for now though. I set up my link in my menu to run as root and use the root path, so I have to insert my root password, I suppose that's only slightly inconvenient considering I only hook my nomad up every now and again.

Incidently, I use kZenExplorer but it's a limitation of the libnjb so it obviously affects any program that uses libnjb in the background.

I hadn't heard of kZenExplorer, I'll have to look into it. Thanks for the tip!
