Subject: [PATCH] usb: storage: do not use UAS with Logitec LGB-4BNHUC
Date: Sun, 12 Dec 2021 20:55:06 +0900	[thread overview]
Message-ID: <20211212115506.180629-1-gnurou@gmail.com> (raw)

This 4-drives USB 3.1 bay gets unhappy when used with UAS:

	sd 10:0:0:0: [sdb] tag#18 uas_eh_abort_handler 0 uas-tag 5 inflight: CMD IN
	sd 10:0:0:0: [sdb] tag#18 CDB: Read(16) 88 00 00 00 00 00 00 9d 42 30 00 00 04 00 00 00

It works perfectly fine as a regular mass-storage device, so prevent UAS
from being used with it.

  * Apricorn USB3 dongle sometimes returns "USBSUSBSUSBS" in response to SCSI
  * commands in UAS mode.  Observed with the 1.28 firmware; are there others?
