Edimax 7711 USB wireless network adapter does not work well on DM8168

Hi, All

We are using a USB wireless network adapter(EdiMAX 7711) on DM8168 EVM to gain WIFI access capability. Right now It's not working so well on the EVM. The gadget may work normally for a couple of seconds and then it looks like the RX direction USB URB can not be submitted in the adapter driver. The same device and linux driver works normally on a Linux Ubuntu desktop.

We know it's very likely the issue is not related to DM8168 USB HW or SW since everything else works perfectly fine with the EVM. 

Just want to find out if anyone else ever encountered the same issue before and if any experience that can be shared related to this product.

Thank you all
