you have loaded the wrong firmware
you need dvb-usb-wt220u-01.fw (do not rename it) also check its md5sum, 
like so
 >md5sum dvb-usb*
782c9937b3f42e5248584570857c8b7f  dvb-usb-wt220u-01.fw
 get driver from here http://www.linuxtv.org/downloads/firmware/  its 
right at the bottom of the list

Also be aware that this card is very sensitive on its aeriel input under 
linux, so if you have amplifier on your aeriel
it will saturate the input, the solution I found was to use a passive Y 
spiltter to reduce the gain.
