usb hub can not work on i.MX6

xiaoqiangyang — Wed, 10 Dec 2014 04:00:59 GMT

Hello all,

I am working on our own designed board based on i.MX6Q. We add a usb hub(usb2514) on our board.

And signal 'USB_H1_VBUS'(pad D10) is connected directly to 5V. The problem is that the hub can not

be find by linux. During boot up,some errors appeared, boot log is bellow:
