hotplug events missing or?

hotplug events missing or?

[Pelle Svensson]

Hi,

It seems that I'm not getting any call to /sbin/hotplug at all.

I'm using a usb memory device and when I unplug/plug the device I will get
a printout on the console saying:

scsi1 : SCSI emulation for USB Mass Storage device
....

and I can get all the information about the device using udevinfo -a -p 
/sys/block/sda


I use an echo line as the debug output in /sbin/hotplug.
I have hotplug support in the kernel (2.6.11.6) and /sbin/hotplug can be 
executed.

Dose anyone knows where to look....


/Pelle

Use /bin/logger to write your debug to syslog.
This should also print the subsystem to syslog:
  echo /bin/logger > /proc/sys/kernel/hotplug

I traced a little bit more and "10-udev.hotplug" (linked to udevend) is
called by an event. But no usb-device comes up in /dev. I can manualy
get one by executing udevstart.
What is the next thing to look for?

Hi,

With some debug info it shows that the daemon failed.
reason for that is it failed to set UDEV_BIN and UDEVD_BIN right in 
udev_version.h
see Makefile line 253 and 254 in version udev-058.

Mixing build root and target root during build. Don't know if I missed it
but I use DESTDIR= pointing to where I have my cross-target root structure.
I this case that is not the same what the target see during executing....

Build system use "/home/pelle/src/rootfs/sbin/..."
Target system see "/sbin/..."

DESTDIR is for packaging targets, prefix for the path's.
