I got this and it seemed like the right item. The box packaging was for HWU8DD, then opened it, tried to use it, and WHOOPS! Looks like Hawking decided to put the model HWU8DDA. Mac only model! However the packaging said "Windows Vista" the drivers say "Windows Vista" and the loose paper said "Windows Vista", however the HWU8DDA is NOT PC compatible. Lovely! I'm now stuck with a $60 worthless device. Or maybe I'll convert to Mac after 20 years, just to use this.....
