Red Hat Bugzilla – Bug 122595
USB devices such as flash disks and scanner not recognized a boot time
Last modified: 2014-03-16 22:44:55 EDT
Description of problem:
When I boot my system with a scanner and/or a flash disk, they are not
recognized at boot time. I always have to unplug the devices and
replug them in after boot.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. plug in a scanner and or flash disk befor boot
2. boot the system
Neither device is present at boot. Only after unplugging the devices
and replugging them in are they recognized
the devices should have been recognized at boot.

Very simple workaround for scanners
We should also be changing the X session startup scripts somewhere to give
console owner permission when a user logs in, but I'm not sure where that's
You can also use Debian-like permissions by creating a "scanner" group and
changing the chomd for a chgrp to that group.
Oops, forgot to mention - that patch is for /etc/hotplug/usb/libusbscanner
Seeing this with a USB cd-rom device. At boot I see:

so it sees it. Then a bit farther in the logs:
Dec 13 10:47:01 lynx kernel: usbcore: deregistering driver usb-storage
Have to remove and reattatch the drive to get the system to see it.
Should note that this is with FC3.
Closing bugs on older, no longer supported, releases. Apologies for any lack of
Please try to reproduce this on a current release, such as Fedora Core 4. If the
issue persists, please open a new issue. Orion - your issue sounds like a kernel
Looks like the USB CD-ROM issue is fixed in FC4.
