You could look at what the device is putting on the air with kismet or
wireshark. Another option would be to see the flow through the driver by loading
the driver with the debug option. The maximum debug level of 5 is likely too
much output, but using 4 should be OK. You need a recent kernel to use this
option. I'm not sure if it is in 3.1 or not. Use 'modinfo rtl8192cu' to see the
module parameter list.
