+== Report from Alex Keda ==
+
+Device is working with "-d usbcypress". Reported within the [http://sourceforge.net/mailarchive/forum.php?thread_name=20100326164007.GA25263%40x61s.reliablesolutions.de&forum_name=smartmontools-support mailinglist].
+
+== Hint/Remark from Stefan Nowak ==
+
+Make sure the first command you send to the device is "-s on".
+After that you can use all the queries/commands you like.
+
+If you first query, and SMART wasn't enabled yet, then you'll get nonsensical  info. And if you then try to enable SMART, it fails.
+If you got into this situation, you have to disconnect and reconnect the device (sort of "start a new session"), and first send "-s on", and from then on all commands works as usual.
+
+That's it. For those who want to see more details, see the logs below.
+
+
+== Correct command order ==
+
+{{{
+$ smartctl -d usbcypress -s on sdb
+# You get the confirmation.
+# And after that, use any command you like.
+}}}
+
+== Wrong command order ==
+
+{{{
+$ smartctl -d usbcypress -a sdb

+Smartctl: Device Read Identity Failed (not an ATA/ATAPI device)
+A mandatory SMART command failed: exiting. To continue, add one or more '-T perm
+issive' options.
+
+# Whatever command you enter from now on fails.
+# Disconnect and reconnect the device, then enable SMART as shown in the chapter "Correct command order"
