Subject: Re: [PATCH v2] usb: core: reduce power-on-good delay time of root hub

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.
