According to [1], 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:

Bug description:
  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
