Subject: patch "usb: storage: Add quirk for Samsung Fit flash" added to usb-linus
Date: Wed, 04 Mar 2020 10:57:53 +0100 [thread overview]
Message-ID: <15833158732147@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
usb: storage: Add quirk for Samsung Fit flash
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: usb: storage: Add quirk for Samsung Fit flash
Current driver has 240 (USB2.0) and 2048 (USB3.0) as max_sectors,
e.g., /sys/bus/scsi/devices/0:0:0:0/max_sectors
If data access times out, driver error handling will issue a port
reset.
Sometimes Samsung Fit (090C:1000) flash disk will not respond to
later Set Address or Get Descriptor command.
Adding this quirk to limit max_sectors to 64 sectors to avoid issue
occurring.
