#263 Gnomad2 fails to open USB interface to Creative Zen Vision W

[Joona Palaste]

I have a Creative Zen Vision W media player. Creative themselves of course fails to acknowledge the existence of Linux, but Gnomad2 still recognises the device. Unfortunately, it cannot open a USB connection to it any more. It used to work back in summer 2010, and all that has changed since then is upgrading my Linux system from Fedora 12 to Fedora 14. When I plug my Creative Zen Vision W to the system, it happily displays a message that I have plugged in a Zen Vision W, and asks me what to do. If I select "Open with Gnomad2", Gnomad2 opens, and displays that it couldn't find any jukebox devices on the USB bus. Here is what I get on standard output:

Device 0 (VID=041e and PID=4153) is a Creative ZEN Vision W.

Here is what I get on dmesg:

The funny thing here is, Gnomad2 used to work perfectly before I upgraded my Linux system from Fedora 12 to Fedora 14. I did not change any hardware on either the computer or the Zen Vision W. I only changed the operating system.

Sounds like a libmtp error to me, try building libmtp from source and then build Gnomad2 from source (making sure all dependencies are met).
