Hello
We are having problem with the USB host interface with MCF5372L
processor. 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...?
Regards
Swaroop
