Hi Greg & Alan, Thanks a lot for your responses. I am not very familiar with the net2280 driver code. I will look into the net2280 driver code and the associated USB mass storage gadget code and will let you know if I have any further questions. I will also go ahead and buy couple of USB3380 PCIe cards and try it out on my system. Thanks again for your time! Thanks, Karthik.
