Not so long ago, I had USB mounting of my iRiver H340 DAP working pretty well into a Fedora 4 system. Recently, probably due to an upgrade, I get odd behaviour where the device is identified, a mount point created, the device mounted and everything appears to be working (ie, I cal see the content and so on). Shortly (ie a minute or so) afterwards, the mount point is removed. This is what I see in the syslog:

Has anyone seen this before?
