Red Hat Bugzilla – Bug 206748
Some USB storage devices unmount and remount when in use
Last modified: 2013-03-05 22:46:36 EST
Description of problem:
Vantec NexStar 3 2.5" external hard drive enclosure and Canon A85 (running on
USB 1.1 channels), will unmount and remount even when in use.
Version-Release number of selected component (if applicable):
Up to date with FC 5 as of today (2006.09.15)
Steps to Reproduce:
1. Plug in external drive or camera
2. hard drive automounts, camera asks to import
3. after a min or few, devices unmount and remount
I will be working w/ the hard drive or not and it will just unmount and remote
the drives automatically (paritions show on destop and gnome drive mounter
applet). I will start importing pics from the Canon A85 digital camera and it
will suddenly stop uploading to the computer and a new prompt to import pictures
Mount and stay mounted
Camera worked on FC3 and 4. Never has worked properly on FC5. Had external
drive for a few weeks. Hasn't worked properly yet. I have the NTFS kernel mod
to read an NTFS partition on the drive. Drive also has reiserfs and ext3.
Kingston U3 1GB Data traveller works fine on the computer.
attached txt file shows the USB key mount. The following sections show the
Vantec drive mount and remount itself.

The issue is not with a drives or drive mount software, but the USB ports
