Default how to remove the kernel message for usb

Hi,
I installed the ubuntu server 12.04 on my EEEBox which do not have CD
driver but only a SD card reader, and I will always get the following
kernel message on my screen continual and repeated:

[ 53.784718] sd 2:0:0:0: [sdb] Test WP failed, assume Write Enabled
[ 53.786833] sd 2:0:0:0: [sdb] Asking for cache data failed
[ 53.786959] sd 2:0:0:0: [sdb] Assuming drive cache: write through
[ 105.496646] sd 2:0:0:0: [sdb] Test WP failed, assume Write Enabled
[ 105.498764] sd 2:0:0:0: [sdb] Asking for cache data failed
[ 105.498889] sd 2:0:0:0: [sdb] Assuming drive cache: write through
............

Anyone know what reason cased this and how to solve this issue? Thanks

Anyother strange two issues I got on my same ubuntu server:
1, when I run "bash" in command, the two shell prompt will print out,
like this(just one Enter pressed after "bash", no more input):
user@rllab:~$ bash
user@rllab:~$
user@rllab:~$

I do not know what case this, it is not a block issue, but I am just
curious why.

2, when I run "sudo -s", I must input password twice to enter root
shell, and I am certain that the passwords which I inputted twice are
correct :

user@rllab:~$ sudo -s
[sudo] password for user:
Sorry, try again.
[sudo] password for user:
root@rllab:~#

Anyone know what happen for this issue? Thanks

This guy seems to be having similar problems, I suggest you watch
there to see if any useful suggestions.
http://askubuntu.com/questions/132100/errors-in-dmesg-test-wp-failed-assume-write-enabled

Meanwhile googling for
Test WP failed, assume Write Enabled
yields lots of hits that might be helpful.

It really is better to ask only one question per posting, if they are
not part of the same problem. The thread gets confused otherwise and
answers will get hung up on one question and others will get
forgotten.
