Subject: Re: [PATCH v4] uas: add no-uas quirk for Thinkplus and Hiksemi usb-storage
Date: Fri, 02 Sep 2022 17:04:02 +0800 [thread overview]
Message-ID: <6311C702.708@126.com> (raw)
In-Reply-To: <6311A323.40100@126.com>
explain for this:
this patch is fixed no speed,not slow speed.
I do not understand, sorry.
---I just checked,I got the disk test data wrong , the high speed is for
usb3.2 , these disks are usb3.0 ,so the slower speed is normal.
the disks of USB3-FW appears to be incompatible with UAS cause crash to
no speed.
Thanks!
