Red Hat Bugzilla – Bug 141384
udev not picking up a multi-card reader
Last modified: 2007-11-30 17:10:56 EST
Description of problem:
I have a multicard reader which is plugged into an internal USB
socket. The card reader also has a floppy drive in it. /sbin/lsusb has
identified the card reader and there is an entry in
/proc/bus/usb/devices for it.
I have done a reset, it looks like something has been picked up as an
error message appears to say that there isn't an entry in fstab or
mtab for /proc/bus/usb
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install the hardware
Other than the error, nothing happens
The device should be installed with an icon in "Computer" with cards
/proc/bus/usb/devices set as a file
Unable to attach the /proc/bus/usb/devices file as a file due to a
bugzilla problem (bug 141385)

The device is correctly identified, but nothing else happens.
Driver=usb-storage should make a hotplug event (for debugging set in
/etc/sysconfig/hotplug: DEBUG="yes") and advertise /dev/sda or s.th.
like that... you may also turn on udev debugging (udev_log=yes in
/etc/sysconfig/hotplug didn't exist, so I've added it in. I'll reboot
shortly and report what happens.
Should /etc/sysconfig/hotplug exist?
On shut down, the message shutting down HAL came up as failed. On
reboot , I had no logging with either udev (nothing in /var/log or
/etc/udev) and had the same error on reboot of can't find
/proc/bus/usb in /etc/fstab or /etc/mtab.
Still using the 1006 kernel, the 1008 kernel gave an error on install
This has been fixed in later kernels
