Scanner not found after udev update

Hi.
I can't find my scanner anymore as normal user. As root it works.

A bit of research showed me this in pacman.log:

[2011-10-25 00:58] ATTENTION UDEV:
[2011-10-25 00:58] ----------
[2011-10-25 00:58] We now use upstream rules for assigning devices to the 'disk', 'optical',
[2011-10-25 00:58] 'scanner' and 'video' groups. Beware of any changes.
[2011-10-25 00:58]   --
[2011-10-25 00:58] We no longer create symlinks from /dev/<dev> to /dev/<dev>0.
[2011-10-25 00:58]   --
[2011-10-25 00:58] For security reasons, we no longer add devices to the 'storage' group. Use
[2011-10-25 00:58] udisks and friends, or add custom rules to /etc/udev.d/rules/, if you want
[2011-10-25 00:58] this functionality back.
[2011-10-25 00:58]  --
[2011-10-25 00:58] We no longer create the static nodes on install needed for an initrd-less and
[2011-10-25 00:58] devtmpfs-less boot, this only affects fresh installs.
[2011-10-25 00:58] ---------------
[2011-10-25 00:58] upgraded udev (173-3 -> 174-1)

So I downgraded udev and makeinitcpio and it works. But how can I access my scanner with the latest udev package?

I am already in the group 'scanner'.

My scanner is:

$ scanimage -L
device `genesys:libusb:001:005' is a Canon LiDE 60 flatbed scanner

Thank you.

Re: Scanner not found after udev update

Do you have a custom udev rule for your scanner?  I had one for my LIDE30 and after the udev upgrade I had to delete it in order to get things working again.

Re: Scanner not found after udev update

I couldn't say for sure if this is actually relevant but here goes. I have a usb scanner, it's a Veho, and I couldn't access it in Linux at all. Since I have XP in VirtualBox I tried to enable the scanner in there. XP didn't see it either and so I eventually came across this line which you add to /etc/fstab:

usbfs           /proc/bus/usb   usbfs   devgid=85,devmode=664   0       0

This worked perfectly and as a real bonus it also made XP (in VirtualBox) able to also see my TomTom Satnav!! As yet another bonus Cheese running in Linux now also sees my Scanner!! Happy days!

Hope this helps
