it's quite risky, bought 4 so far and all are defective. even if you can get them to work, their is problems like random crashes and some don't even post. not worth it imho, i rather buy something new for must less that are obsolete like at compgeeks.com and tigersurplus.com. 1 out of 4 that I have not thrown away, had this usb 2.0 problems that everytime I try to install the driver, it would crash upon boot up. so it stays disabled for the time being. heh, and it costed me 39 bucks. most likely you have to return them, and usps charges alot for even postal mail like 9-11 bucks 1 mobo, 13-15 for 2 mobo and so on. ask yourself this, what are the chances of someone returning a perfectly working motherboard?
