| 1 | == Report from Alex Keda == |
| 2 | |
| 3 | 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]. |

| 5 | == Hint/Remark from Stefan Nowak == |
| 6 | |
| 7 | Make sure the first command you send to the device is "-s on". |
| 8 | After that you can use all the queries/commands you like. |
| 9 | |
| 10 | 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. |
| 11 | 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. |
| 12 | |
| 13 | That's it. For those who want to see more details, see the logs below. |

| 16 | == Correct command order == |
| 17 | |
| 18 | {{{ |
| 19 | $ smartctl -d usbcypress -s on sdb |
| 20 | # You get the confirmation. |
| 21 | # And after that, use any command you like. |
| 22 | }}} |
| 23 | |
| 24 | == Wrong command order == |
