Hi,
On a mx28 custom board with a USB hub I can get a USB stick to get
detected after applying this change:
http://marc.info/?l=linux-usb&m=145079935324339&w=2
Things work fine if I boot without the USB stick connected. Then I can
insert/remove the USB device and it always gets detected.
However, if I boot with the USB stick connected I get:
[ 2.968513] hub 1-1:1.0: USB hub found

[ 3.654557] usb usb1-port1: Cannot enable. Maybe the USB cable is bad?
[ 3.661650] usb usb1-port1: unable to enumerate USB device
And the only way to get the USB port working again is to remove the
USB stick and reboot the board.
Commit d0ee68b59e6aa33221 ("usb: phy: mxs: Add VF610 USB PHY support")
shows the same error messages in the commit log, but trying the same
approach of adding the MXS_PHY_NEED_IP_FIX flag does not help on mx28.
Any suggestions?
Thanks,
Fabio Estevam
