Three month ago, My USB 3.1 device cannot be detected after upgrade
kernel from version 5.10.41 to 5.10.42.
And I found some other people ran into the same issue:
https://forum.manjaro.org/t/kernel-5-10-59-doesnt-detect-a-connected-usb-external-disk/79320
https://forum.manjaro.org/t/how-to-make-active-usb-hub-work-in-manjaro/84548
Two days ago, I try to fix the issue myself, and I found out that it was
cause by this patch. After revert this patch, my USB 3.1 device can be
detect again.
I have already file a bug on here:
https://bugzilla.kernel.org/show_bug.cgi?id=214875.
