If you don't need the latest kernel, you may find this thread on the Freescale Coldfire forum helpful...

We are using the MCF532X platform uClinux kernel (kernel message attached below). When we connect the USB Flash mass storage device, the processor detects this as a Full speed USB device, but when requests for the device descriptor ~sometimes this returns -110 as error code otherwise stops responding. Could you please help me on this...?
