view story

http://chakra-project.org – Hi there,IU'm trying to access an MTP based music player through amarok (a Creative Zen Mosaic). When plugged in, the device notifier recognizes it as a portable media player, but it won't mount and Amarok doesn't see it.Following some investigation and suggestions from the Amarok team, I tried mtp-detect and got this:[user@computer ~]$ mtp-detect libmtp version: 1.1.3Listing raw device(s)Device 0 (VID=041e and PID=4161) is a Creative ZEN Mozaic.   Found 1 device(s):   Creative: ZEN Mozaic (041e:4161) @ bus 3, dev 7Attempting to connect device(s)usb_open(): P (HowTos)
