** Description changed:
Hopefully I have time to root-cause this.
We have two Kubuntu 12.04 LTS machines. One of them has a USB card
reader, which we want to leave permanently attached. We use it to
upload photos to Digikam several times a month.
Recently we noticed the card reader not working. It showed up in lsusb,
BUT "ls /dev/sd*" showed only one device (the internal hard drive).
WORKAROUND: Unplugging the entire card reader and plugging it back in
again fixes it.
WORKAROUND: The following fixed it without re-plugging the cardreader:
modprobe usb-storage
+
+ WORKAROUND: This was caused by my enabling MODULES=dep in /etc
+ /initramfs-tools/initramfs.conf. Changing it back to MODULES=most fixes
+ it (and adds back 2 seconds to the boot time).
