I am using Windows xp home edition and bought a adstech 2.0 usb drive kit and installed a Sony 810a Dvd recorder in it. I set the dvd recorder to master and plugged the drive kit in by usb to my computer and it reconized it but in device manager it shows an exclamation point in front of it and in disk management it shows my hard drives and cd roms in my computer but not the sony drive or drive kit. My usb is okay because I use an external hard drive in it. Do you have any answers to what is wrong.
