Bug#733651: general: Any USB card reader works only after being replugged.
Package: general
Severity: grave
Justification: renders package unusable
Dear Maintainer,
*** Please consider answering these questions, where appropriate ***
After system reboot or replugging USB card reader into USB slot, the SD or MMC
or Memory Stick card appears in /dev/disks/by-id, say as /dev/sde, and in
Nautilus panel.
After unmounting it from Nautilus or from command line it disappears as it
should.
But if memory card is pulled out and inserted again, it does not appear again
in Nautilus and dmesg shows no reaction.
At the same time the device /dev/sde still exists, even if memory card is
absent.
If I issue "fdisk -l /dev/sde" with inserted card, it appears in Nautilus and
in dmesg:
[ 4713.404064] sd 6:0:0:0: [sde] 62666752 512-byte logical blocks: (32.0
GB/29.8 GiB)

[ 4713.824733] EXT4-fs (sde1): mounted filesystem with ordered data mode. Opts:
(null)
If I unplug the mamory card, dmesg says:
[ 4779.180564] sde: detected capacity change from 32085377024 to 0
This behaviour began in september 2013 as far as I remember.
It was annoying, I thought my card reader was broken and I replaced it, but
problem still remained.
So it is a bug.
Affects cryptdisks as the key is stored on SD card.
