Before that, can you pinpoint more closely when the problem appeared? Is
it there in 2.6.21 already? Bisect a few times to narrow it down even
further?
git bisect start
git bisect good v2.6.20
git bisect bad
.. go, gadget, go!

Wait, we have not had a /dev/scanner since the 2.4 days. For all of the
2.6 releases, usb scanners are controlled from userspace by xscane, not
the kernel.

What works ok? Xscane? Or some external kernel driver?

Do you have CONFIG_SYSFS_DEPRECATED enabled? If not, please read the
help entry for it and enable it. Please let me know if this solves your
problem or not.
Also, what distro release are you using?

check that we have

Who creates that? udev? What udev rule does that?
Can you run 'udevtest' to see what is supposed to be matching here?
Odds are you have a broken rule somehow.

This last device is correct, and what your udev rule should be using to
create your symlink.
You didn't answer my, "what distro are you using" question. Also, what
package created the udev rule that creates the above symlink?
thanks,

And if you run that 'udevtest' command on 2.6.21 what happens?
Again, you have not shown me the udev rule that adds that symlink, is it
something you added by hand, or something that Fedora added to the rules
file?
thanks,

I don't see anything odd there at all.
Can you run 'git bisect' to try to narrow down to the patch that caused
the problem?
thanks,

Is CONFIG_USB_DEVICE_CLASS enabled in this kernel?
Are _any_ files showing up in /dev/bus/usb/?

greg this is part of my config
(we are talking now 2.6.22-rc4-200706042030-cfq7 #160 SMP PREEMPT Mon
Jun 4 20:55:02 CDT 2007 x86_64 x86_64 x86_64 GNU/Linux)
CONFIG_USB_DEVICEFS=y
# CONFIG_USB_DEVICE_CLASS is not set ---------------------
# CONFIG_USB_DYNAMIC_MINORS is not set
CONFIG_USB_SUSPEND=y
# CONFIG_USB_OTG is not set
i disabled libusual in my config
# CONFIG_USB_LIBUSUAL is not set
with libusual=y my usb-harddrives doesn't show up on desktop after
boot until i cycle one off/on and from this moment all of them start
showing up
with libusual not set -usb-harddrives shows up but this doesn't affect
scanners
btw scanners are working with standard fc7 86-x64 kernel

Great, thanks for verifying this. This config option is by default
enabled, so you need to work hard to disable it :)
thanks,
