Subject: patch "usb-storage: Add compatibility quirk flags for G-Technologies G-Drive" added to usb-testing
Date: Thu, 24 May 2018 18:20:21 +0200 [thread overview]
Message-ID: <15271788216388@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
usb-storage: Add compatibility quirk flags for G-Technologies G-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-testing 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 be merged to the usb-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Subject: usb-storage: Add compatibility quirk flags for G-Technologies G-Drive
The "G-Drive" (sold by G-Technology) external USB 3.0 drive
hangs on write access under UAS and usb-storage:

The proposed patch adds compatibility quirks. Because the drive requires two
quirks (one to work with UAS, and another to work with usb-storage), adding this
under unusual_devs.h and not just unusual_uas.h so kernels compiled without UAS
receive the quirk. With the patch, the drive works reliably on UAS and usb-
storage.
(tested on NEC Corporation uPD720200 USB 3.0 host controller).
