Re: RK3288 USB Issues

[Norbert Lange]

Hello,

did you try without your patches, to see if you can reproduce the problem?
I can fix my issues if I disable usb autosuspend

To narrow down the causes I can think of:
*) Some hardware issue only on my side -> please try to reproduce it
with an unpached kernel
*) Some other stuff I modified -> gonna try a clean kernel with just
your patches (hopefully will find time on sunday)
*) Maybe some different kernel config options -> mine are
multi_v7_defconfig with a few modules added

Kind regards,
Norbert
