I have installed the card reader onto the system and it shows up in bios but not the computer part of my windows 7 where it lists all my hard drives and removable storage. I have used the usb ports on it and they work. I also have downloaded and installed all the driver packages from roswill homepage. Have tried to find a online compatiablity list and could not find one. I have the usb molex and sata cables all conected to the motherboard. In my knowledge is if it shows in bios it should work. Someone please help.
