I have several USB drives i have tried -- each with varying levels of success(thought it was the way i was loading them).
last one i tried was a newer PNY 16G not sure of the model number. I manually backed up the files then replaced the image file with Anna's proliant fix, then ran make bootable, then safely removed.
The first time i tried was with an old Patriot XT 4G, that time i used the UNRAID usb creator with no mods, then i did the same with the manual process above with no better luck. the cli is available in every case, web gui is not there and neither are the nics.
