Public bug reported:


In order for the Zen Mozaic device to work with gnomad2 and other libmtp devices, you need this udev rule in:
  libmtp8: /etc/udev/rules.d/45-libmtp8.rules
and possibly:
  libmtp8: /etc/udev/libmtp8.rules

# Creative ZEN Mozaic
ATTR{idVendor}=="041e", ATTR{idProduct}=="4161", SYMLINK+="libmtp-%k", MODE="666", GROUP="audio"

I got this information from here:
  http://doc.ubuntu-fr.org/creative_zen

but have since tested it with my own device and it fixed the issue for
me.

An entry appears to be present in the upstream source.

  logs/mtp-detect-creative-zen-mozaic.txt

They advertise the device as working.  It appears the libmtp8 version in
Ubuntu is quite old (v.0.3.5 is now current, v0.3.0 is in Jaunty) .
Will it be updated before Jaunty is released?

Below is the lsusb output I see from the device.
