USB not working with caches.
Using clover. HP Compaq dc7900 cmt
It started when i updated to 10.9.3.
I also have this problem with the 10.10 installation but because it only boot to the caches, i can't install.
I have tried: USBBusFix, the legacy flag, using clover usb fix.
Please help, I don't have any problems with my mac right now, but the boot time is long and i really need 10.10.
