Since it may be your better language it might be best to seek more help there.
Any rate there are threads here (at least in English) the describe how to mediate the sound problem. You will just need to search a bit for them.
As for the usb problem, can you provide more details?
Maybe plug the key in wait a few seconds then type lsusb at the command prompt and look for the key to be listed there.
If that fails you then you might try posting that info here in this thread.
