i.MX6 USB Mass Storage Driver Problem

Hi all,

     I have a problem about usb mass storage driver, that's it can't enumerate my mass storage device.

     but it can enumerate my mouse, keyboard...etc hid device.

     anyone have idea about it ?

     I always get below messages when my mass storage device plugs in.

Hi, I'm having the same issue, investigating now.  Have you made any progress or have a solution?

I'm not using the OTG port, but I am getting similar messages.

Hi Ken,

My issue had been fixed…but I didn’t do anything, that’s HW issue.

Best regards,

Hi wangyc,

This was posted as a document, and not as a discussion. I think you are more likely to get a response if you re-post it as a discussion. You can do that by following this link:

Let me know if this helps.

Hi,

Maybe the difference between mass storage and HID devices is the speed.

Is this a custom board? Then check the layout and routing of the USB differential data lines.

Also, do you supply the USB PHY of the i.MX6 properly?
