If you just want to buy a special box for hp china, in my opinion it is best to box CPF II. No need to modif the cable, can be used / combined with other software, can detect the usb cable, can be used to help dismantle cas. And many more advantages. Believe ... you will not regret buying this box. Infinity is good but you have to make their own cable, it means you need to know about the pinout.
