Hi,

Mobo: Gigabyte GA-Z270M-D3H

After trying all of the clover command line options I've read here in the forum regarding a means to get passed the "Still Waiting For Root Device" (with no success) I think I have concluded that in my case the issue is the USB interface.

The USB thumb drive I am using operates @ USB3.0

The Mobo has 6 USBs pre-wired and available but NONE of them are USB2.0; it does offer 2 USB2s if I choose to build a connector and wire it to the pins on the Mobo.

So, my questions are:

A. are there 'connector/adapters' that will fit the 10-pin USB2.0 header on the Mobo and bring out the USB 2.0?
or
B. If I found a 16-gig USB2.0 thumb drive would that fix this issue?

And while I have your attention why does the Unibeast fail to find an 8gig formatted thumb drive but does find a 16gig?

thanks,
tony

A) What you want is such a bracket:

B) You can try. I have heard of similar cases where using a USB2 stick instead of USB3 stick worked.

As to why Unibeast fails to find a 8GB formatted USB stick, the reason is the lack of sufficient space on the stick after the formatting. I experienced this myself before and investigated the reason behind. I was a bit surprised to find out that not all 8GB USB sticks have the same capacity after formatting. I have some Sandisk USB2 sticks that contain a bit more space than Toshiba 8GB USB2 sticks. I was able to make a El Capitan Unibeast USB stick (UEFI) using the Sandisk sticks but not with the Toshiba sticks.

Thanks, 007 ! I'm going to go with the USB2 cabling thingy; It'll be a nice (permanent) addition to the Hack.
