I have a 500gb kaser storage vault and its usb2 compatable but i only get usb1 transfer speeds. I have sp3 installed, I've updated drivers for the drive, i installed a new usb2 driver, i made sure the usb2 setting in the bios was on, i've uninstalled all my usb devices and restarted my computer with them plugged in, i have an inhanced usb controller but whatever port i plug into it says high speed device plugged into a nonhigh speed port. Im stuck and have nowhere else to turn. any help would be greatly appreciated.
