 Hello,

 

Can you please take a trace of the USB traffic using any of the USB bus analyzers (like CATC/ Ellysis, etc). Attach the same here so that we can analyze.

Gayathri

Did you run eye diagram to see how good the signal quality of the USB interface of your board is??

Do you have a FX2LP DVK? Did you try connecting one to your PC to see if it is not a issue with your PC??

Did you try it in other PCs to isolate whether it is a PC issue??
