Detecting Full Speed USB device in imx6

[teddy123]

Hi Everyone,

While trying to test USB port of my custom imx6 board with various USB devices, I encountered the following problem while using a SD card reader(Full Speed Device).

usb 2-1: new high speed USB device number 5 using fsl-ehci

hub 2-0:1.0: unable to enumerate USB device on port 1

Does this problem  is due to my hardware/software configuration?

Hi teddy

i.MX6 hardware and Freescale BSP supports USB Full Speed

without restrictions. Probalem my be in custom board or

specific driver is needed for this USB device.

One can narrow down problem attaching this device to

Freescale reference board with Demo images or trying other

Full Speed devices.

Best regards

igor

Hi Igor,

The problem seems to be in software side. I have tested with recent Linux BSP and its working fine. But am using Linux kernel version 3.0.35 for porting Android. Any Idea how to overcome this?

Hi teddy

I think you can contact vendor of that device for driver for

Linux kernel version 3.0.35.
