The following line needs to be added to /etc/udev/rules.d/65-mtp.rules to resolve this: # Creative Zen Vision:M 60GB SYSFS{idVendor}=="041e", SYSFS{idProduct}=="4151", SYMLINK+="libmtp-%k", GROUP="plugdev", MODE="660" Note the different idProduct entry. I'm assuming the existing line for the Zen Vision:M corresponds to the 30GB version.
Upstream informs me that this is resolved in version 0.1.0.
back to herd; maintainer retired...
The powers that be have not granted me with bugzilla rights to add a dependency on bug 159056. See bug 159056 for updated ebuild (which should land in portage soon). This can be marked resolved once that bug is closed.
libmtp-0.1.3 is in the tree, so this can be closed now. it is in package.mask, but it works good in my experience
closing bug, thanks patrick
