wait_for_sysfs, udev

wait_for_sysfs, udev

[Simone Crippa]

Hello,

I plugged in into my USB port a palm tungsten and tried to hotplug, which 
resulted in the daemon.log entry:

Oct 27 12:34:54 nx7000 wait_for_sysfs[8184]: error: wait_for_sysfs needs an 
update to handle the device '/devices/pci0000:00/0000:00:1d.0/usb1/1-2' 
properly, please report to <linux-hotplug-devel@lists.sourceforge.net>
Oct 27 12:34:54 nx7000 wait_for_sysfs[8186]: error: wait_for_sysfs needs an 
update to handle the device 
'/devices/pci0000:00/0000:00:1d.0/usb1/1-2/1-2:1.0' properly, please report 
to <linux-hotplug-devel@lists.sourceforge.net>

I have a Debian system (testing) with udev 0.034-1, hotplug 
0.0.20040329-1 and libsysfs1 1.1.0-1 . Don't know what is relevant, if you 
need more info, mail me back.

Since I have reported a similar error message before, I already tried with 
udev version 0.040 from:

http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev-040.tar.gz

it resulted in the same error:

Oct 27 12:38:06 nx7000 wait_for_sysfs[8484]: either wait_for_sysfs (udev 040) 
needs an update to handle the device 
'/devices/pci0000:00/0000:00:1d.0/usb1/1-2' properly (no bus device link) or 
the sysfs-support of your device's driver needs to be fixed, please report to 
<linux-hotplug-devel@lists.sourceforge.net>

I hope I can help further. Is it possible that there are so many errors left 
in udev? Before I switched from devfs to udev some weeks ago, I didn't have 
these problems.


Greatings, Simone

Yeah, we have currently no quick fix for that, sorry. libsysfs is unable to
determine the "bus" value of that device. The message itself does not mean
anything critical. We will hopefully fix that (message) soon.

Thanks,
Kay
