I also have a similar device, which I've been messing with a bit the
last couple of days. In your case, it isn't seeing the media, just the
"drive". I've had to try various combinations of unplugging the adapter
from usb, inserting the media then plugging it back in. It does seem to
work fairly reliably if you boot with the media already inserted, but it
doesn't seem to detect media change at all.
I get around it (on my cheap reader) by always doing a
cat /dev/null > /dev/da1
whever I change or insert new media into the reader
That seems to work with the gear I have 99% of the time.
