Maximus IV usb 3 port problems

Woodsman444

Hello I have two problems with my board not all of my hard drives show up,they are all connected with sata 6 cables,and some of my rear usb ports do not function all the time.Seven internal drives show up but not the eighth and I bought a 4 port sata extension card but cannot get that to work after installing programmes off the disc. I have a 4 port hub that I try and run some externals but with my usb 3 ports being tempremental not all of them turn up either,so I would appreciate any advice that might teach me what I am doing wrong.
Thanks
