This key's easily installed without any drivers (drivers) and works instantly, but the best is still not install it at all, and do not buy it either. The sound quality is atrocious, never heard anything like it and yet ... the blender is nonexistent, the adjusted level is virtually impossible.
I strongly advise against buying this product and all other built from the same chipset namely: TP6910 Tenx of technology, which incidentally was originally designer to make IP phones and not sound cards!
