Hello,

I am using i.MX53 QSB with Linux. I am facing problem with on board USB.

It is unable to populate the device USB devices. I have connected a

Dell Optical mouse(Model: MS111), on the serial console i could see the following prints.

and for about 20 iterations board gets restarted. I am using prebuilt linux images downloaded from freescale.com

please download the BSP (L2.6.35_11_09_ER_SOURCE) and apply the patches (IMX53_LINUX_1109_BSP_PATCH).

please try to build the image and then run it on the board.
