14cd:6116 does not work with usbcypress

kpajko79
Hi!

I have recently got some no-name 2.5" USB enclosure as a gift when purchased my harddisks. It's working OK, and I'm happy with it. Yesterday I was just curious and checked the database of supported USB enclosures of smartmontools, and having found it on the list caused me a little bit surprise, as I was not expecting it at all. But unfortunately smartctl does not work.
Below you can find the output smartctl gave me, and the complete information of the device given by lsusb, and the dmesg part about the device detection. Actually these outputs are from an ARM system, running 2.6.38, but I've got the same result trying it out on an x86_64 at my workplace, running 3.0.0.
The enclosure has a single chip, M6116A. Based on the supported device list, usbcypress should be able to handle it. The HDD behind it is WD5000BEVT, if that's important.

(I know it's not the latest 5.42, but I couldn't find relevant changes in the changelog, and have no time to give it a try - maybe on the weekend.)

(Adding -T permissive did not help anything.)

This device was added due to this report:
http://sourceforge.net/mailarchive/message.php?msg_id=27015473

Does 'smartctl -d sat ...' possibly work?

Thanks,
Christian
