Yocto iMX28 linux-fsl 4.1 kernel USB issues

We are evaluating the Yocto linux-fslc 4.1 kernel for the Freescale imx28 processor. We are running it on an imx28 platform and are seeing issues with the USB functionality. It is getting an error when trying to enumerate a USB modem. The modem is connected to the imx28 through a HUB. It is getting the following error when attempting to enumerate the hub.

 

usb usb2-port1: cannot reset (err = -32)

 

Does anyone have experience running this kernel on an imx28 platform?

How complete is the USB support on this version of the kernel?

Does anyone know or have heard of similar USB issues on imx28/ linux-fsl 4.1 kernel?

 

The board works correctly on a Yocto freescale 2.6.35 kernel so we know it is not an issue with the board.

 

Thanks,

 

Bruno
