No. But udevstart prevents later firmware upload. In the future udevstart will 
be dropped permanently so will not be an issue.

There are several ways of loading firmware:

Usually the firmware is loaded by this line of udev.rules (included in lunar):
ENV{UDEVD_EVENT}=="1", RUN+="/sbin/udev_run_hotplugd"

or can be loaded by:
ACTION=="add", SUBSYSTEM=="firmware", RUN+="/lib/udev/firmware_helper"
or
ACTION=="add", SUBSYSTEM=="firmware", RUN+="/lib/udev/udev_run_hotplugd"

The way I load firmware depends on udev version. If all these ways fails I 
downgrade to last working udev and wait for next release.
Since few recent udev releases the official way of loading firmware using 
firmware_hepler is finally working.

This usb device I use is ADSL Speedtouch 330 modem.

but udev config is described here:
