Ok i have a usb 2.0 hard drive and usb 2.0 cd burner. i have a usb 2.0 cardbus with 4 port. My problem is when i connect my external hard drive into usb 2.0 cardbus it transfer file slower than usb 1.1. Many times it crashes my computer. Mu cd burner never starts to burns anything when i attemp to burn something. It starts as if it's going to burn but it just dosnt start burning. What do you think the problem is?
