JMicron 152d:0539 JMS539 with bcdDevice 1.00 requires -d sat in conflict with existing drivedb.h entry

[Christoffer Hammarström]

I recently got a new SSI-1359RUS3 hard drive enclosure (152d:0539 JMS539 with bcdDevice 1.00), because i had an identical box that i bought a few years back, that was working well (152d:0551).

The vendor page is at ​http://www.ssi.com.tw/en/goods.php?act=view&no=33

The only problem i had with the older box is that it's impossible to read smart data from the first drive in the box, but it otherwise works fine.

Apparently the boxes turn out to have different firmware, though they seem physically identical.

I'm running both boxes in JBOD mode.

When smartd tries to read from the first drive in the new box (152d:0539), the usb disconnects and reconnects, failing my raid.

It took me a while to figure out that the new box requires "-d sat", where drivedb.h has "-d usbjmicron". for "0x152d:0x0539", "0x0100".

I changed "-d usbjmicron" in that entry in my drivedb.h to "-d sat", and the usb no longer disconnects when smartd tries to read from the first disk in the box.

lsusb -v output follows:

# lsusb -d 152d:0539 -v
