I notice you're one of the israeli teams, so I presume you're operating on 220V/50Hz power. The power adapter we were given in the kit (here in the US) is a 12V, 1000mA adapter rated for 120V/60Hz power. If you're using this adapter, it would be putting out significantly more voltage, in the 20V range, which might be cause the problem. Or, if you're using a different adapter, you should make sure that it's rated for a 12V, 1000mA output. If your adapter isn't putting out the correct power, it could be affecting the operation of your USB devices, which need a certain amount of 5V power to operate. This is more likely to be a problem if your adapter is putting out too low a voltage, but you should still check to make sure you're powering the DS properly.
