USB WIFI doesn't work on AM335X board

Hi,everybody

I want to use USB WIFI  named RTL8192CU on AM335x board. My  wifi module is connected  to the board via USB port , but it doesn't work.

When I reboot kernel which consist of  the driver of WIFI module,it can't  initializes usb and the system stops there.

I use the kernel that the version is linux-3.2.0-04.06.00.08. I think the driver is ok

Does the kernel support  USB WIFI.

How can I go on? Could you give me some advice please?

Thanks And Best Regards!
