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
