Description of problem:
After switching to F15 (with all updates until today), when I plug in my Archos 3 Vision MP3 Player, the devices (e. g. sdc) appears for a few seconds and then it's gone again.

With previous versions (F13, F14) the device was available below /dev until I unplugged the device.

My USB stick (Corsair Flash Voyager 8GB) stays until I unplug it.



Version-Release number of selected component (if applicable):
udev-167-4.fc15.i686



Steps to Reproduce:
1. Plug in MP3 player
2. Device appears in /dev
3. Device dissappears automatically one second later automatically again.



Expected results:
Plug in the device, sd* device appears and stays available until device is unplugged.
