Have you set CONFIG_PM?
Yes. CONFIG_PM=y.
Can you reproduce the problem with this kernel?
I reproduced the U1/U2 disconnect issues several times. I didn't try the
issue of not enough bandwidth for two devices.
Can you please try the not enough bandwidth issue?
Can you cat /sys/bus/usb/devices/2-2/power/usb3_hardware_lpm_u1
and /sys/bus/usb/devices/2-2/power/usb3_hardware_lpm_u2 for several
times? Don't use that device when cat these two files.
I am hoping that LPM works when only one device is used (hence
there is enough bus bandwidth).
