it appears this motherboard is using usb 3 aka xhci. i don't know for
certain but i don't think any plan 9 (fork or not-a-fork) has xhci
support. looking through the archive, there was talk of xhci about a
year ago.

try disabling usb 3.0 in the bios setting and see if it makes progress
when booting from usb.
