udev errors for usb modems after kernel upgrade

[Deniz Eren]

Hi;

After upgrading my kernel from 2.6.18 to 3.5.3. I started to get udev
errors when I plug in my usb modem device(errors are below). I think
this is causing my usb_modeswitch not to work properly. Same error
occurs for usb-storage devices too. Can you provide a solution or what
is the cause?

udev version: 095

udev version: 095

Try also updating your version of udev, 095 is very old, and matched up
with what 2.6.18 was. Now that you have a newer kernel, there's no
reason to use such an old udev.

good luck,
