I would try "sudo fdisk -l /dev/sdb"
If it does not show any suitable filesystems, then that's the problem
and not any file permissions.

I can see USB in terminal in /dev. However I can't see the sdcard.

Is the sdcard card reader recognized? I _think_ yes.

I tried a rescan but no help.
echo 1 | sudo tee /sys/bus/pci/rescan
Shouldn't the drives be shown in /media?

I see a little plus sign. Maybe I changed something here a while back
and forgot. Maybe this is an acl or permission issue? So now I'm
thinking maybe just leave the USB and sdcard in and reboot. Maybe
root will set them up on initialization. Didn't work.
Interesting errors on reboot in auth.log but after investigation I
think it is cruft from pam that can be ignored.

Let's check media directory permissions.
eric@dragonEnvy:/media$ getfacl eric
# file: eric
# owner: root
# group: root
user::rwx
user:eric:r-x
group::---
mask::r-x
other::---
Oddly I can plug in a mouse or my iPad and everything works fine. I
plug in an USB dongle or my little SandDisk card and nothing. What do
you think? Where else to look?
Thanks for any tips!
