Subject: patch "USB: Add NO_LPM quirk for Kingston flash drive" added to usb-linus
Date: Tue, 03 Nov 2020 10:19:34 +0100 [thread overview]
Message-ID: <160439517412187@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
USB: Add NO_LPM quirk for Kingston flash drive
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: Add NO_LPM quirk for Kingston flash drive
In Bugzilla #208257, Julien Humbert reports that a 32-GB Kingston
flash drive spontaneously disconnects and reconnects, over and over.
Testing revealed that disabling Link Power Management for the drive
fixed the problem.
This patch adds a quirk entry for that drive to turn off LPM permanently.
