I am having a problem with my usb card. I just installed a usb 2.0 PCI card but it still seems as though Windows XP is seeing 1.1. When I plug in my Mp3 player my computer acts like it doesn't want to read it. I have read that Windows SP1 or SP2 solve the issue but that is where my real problem lies. When I download either it tells me that my product key is bad. Is there another way around this? Please help...
