Subject: [PATCH 3.2 058/102] USB: storage: Add quirk for Ariston
 Technologies iConnect USB to SCSI adapter

3.2.64-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Mark <markk@...ra.co.uk>

commit b6a3ed677991558ce09046397a7c4d70530d15b3 upstream.

Hi,

The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g.
iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM
Microsystems chips. Only the connectors differ; both have the same USB ID.
The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other
than 0.

I don't have one of these, but based on the other entries for Shuttle/
SCM-based converters this patch is very likely correct. I used 0x0000 and
0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which
bcdDevice value the products use.
