Hello.
I've got a problem with my arduino(link), and noone can help with it.
Maybe someone can help me with advice how to check if arduino board works?

You have already determined that your Arduino Leonardo DOES NOT work.  Since the USB interface isn't working ("Unknown USB device(Device Descriptor Request Failed)") I would expect either a bad connection or failed firmware.  Try re-uploading the Leonardo firmware to see if that helps.  You may want to spend the $4 or $5 to get a USBasp or USBtinyISP from eBay.  They make firmware uploads much easier.
