AutoSense failed

[Pawel Worach]

Hi,

Got two new 1TB Seagate Desktop USB drives that I plan to mirror however doing some I/O to the mirror or forcing a rebuild causes some CAM errors, no idea if this is CAM or USB related. Any ideas about this ? Missing quirk ? Any special debug output requests ?

The iProduct and iSerialNumber data seems to randomly fail to be retrieved.
