Hi Alexandre,
I'm new to kernel development. I want to explore this bug. From you

To sum up:
Most of the time, my HP USB 3.0 hard drive will not be properly
mounted when booting or when connecting it.
I usually end up with something similar to the following in dmesg:

To make it work, when the USB drive is already plugged in, if I can
disconnect it and reconnect it in the USB 3.0 port fast enough, it
works most of the time.
This problem is not seen under Windows.
According to Windows Hardware Certification Requirements (part 1):
"Next, the time between the time that RxDetect succeeds and the time
that the device enters U0 can be up to 300 ms. With an extra margin
for hub control transfers and other delays, the total comes to 500 ms."
Also, when the hard drive is plugged in a USB 2.0 port, it works like
a charm.
Are we too aggressive when we are "waking up" the device?
