you don't put anything in yourself. you should be following the instructions included with the USB card. that should include a device driver disk.
I have a problem with windows xp professional.
I keep getting a splash come up saying "cannot find USBEHCI.sys" I have found this file on the web & downloaded it. I have just put in a USB2 PCI card, is this the cause? What I need to know is how to replace this file. e.g. where do I put it?
Hope someone can help.
