usb hub can not work on i.MX6

xiaoqiangyang · ‎12-09-2014

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:

Hi Xiaoqiang

this may be as below link,

most probably it’s a result of hardware failure rather than a driver or kernel bug. USB has

an over-current protection, which gets triggered when power consumption from the port is too high.

Dear igor,

Our crystal for USB hub has something wrong, we replaced it and solved this problem. Thanks a lot.
