I had previously tried  sd[a-c], but did it again, this time  sd[a-g].
sda gives  "no medium" and sd[b-g] gives "not valid block dev"  as=20
before.

Unplug and replug makes the following three lines in /var/log/messages.

Dec  1 21:01:49 bertha kernel: usb.c: USB disconnect on device 3

mount /dev/sda ....  makes the following lines in /var/log/messages

Since this reader has slots for two different types of media, I wonder=20
if the software is checking for a CompactFlash card first.  And if so,=20
how to get to the smart media card fitst.
