Update Cosy131 Firmware

I have a Cosy131 in firmware 8.2s1 and i would like to be up to date. It’s impossible to do the update with eBuddy so i tried with a USB card, i followed the steps in the PDF support but it didn’t works. The USR Led didn’t flash orange like if the eWon didn’t see the USB card. Can someone help me?
