Hi all,
Sorry for bothering you but I would like to know whether there are
updates on this or not.
This problem is affecting many people and has been identified, it
would be a pity not to have a fix upstreamed.
Let me know if I can help somehow.
Right, there is a test patch in my tree, in the remount_fix_test branch,
based on 4.8-rc6
git://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git
remount_fix_test
I was about to go through the remote wakeup flags for this before I
got pulled
into other things. If you can try it out and see if works for you it
would help.
Hi Mathias,
Sorry for my "ping" email, since I saw no more emails I thought no
progress has been made.
I managed to test your code today by plugging and unplugging the drive
many times from both USB 2.0 and 3.0 ports, they work just the same now,
without a issue.
Here are dmesg excerpts:

Thank you so much for the fix. If there is still something I can do,
just let me know.
Best Regards,
Marco
