According to , the :u quirk mentioned in this bug is equivalent to
US_FL_IGNORE_UAS, which completely disables uas. The US_FL_NO_ATA_1X quirk can
be specified in modprobe.conf as :t. I'm not sure what that quirk does.
Unfortunately I can't test this against my STEA1000400 as it is
currently in off-site storage, but I'll try this when I get it back.

Seagate external drive causes SCSI bus resets when UAS enabled
Status in linux package in Ubuntu:
Seagate STEA1000400 external USB hard disk (USB ID 0bc2:2322) causes
continuous SCSI bus resets by default. As a workaround, disabling UAS
causes the device to work fine.
To disable UAS, I created a file in /etc/modprobe.d with the following
options usb-storage quirks=0bc2:02322:u
