Just like all previous UAS capable Seagate disk enclosures, this

So far we've been adding quirks for Seagate drives on a one by one
basis (I started this myself) hoping that one day they will fix
their ATA_1X pass-through support. But that does not seem to
be happening.
Maybe we need to do something like this instead ? :
--- a/drivers/usb/storage/uas-detect.h
+++ b/drivers/usb/storage/uas-detect.h
@@ -111,6 +111,10 @@ static int uas_use_uas_driver(struct usb_interface *intf,

+ /* All Seagate disk enclosures have broken ATA pass-through support */
+ if (le16_to_cpu(udev->descriptor.idVendor) == 0x0bc2)
+ flags |= US_FL_NO_ATA_1X;
+
usb_stor_adjust_quirks(udev, &flags);
if (flags & US_FL_IGNORE_UAS) {
Then we can remove a whole lot of quirks and we avoid future
churn when new Seagate device ids show up.
Regards,
Hans
