Comment(by pgf):
initial experiments using mitch's recipe below, and manipulating
bits 22 and 23 of USBD-MMIO 13-10h are unsuccessful. (PM pdf p. 144)
it's quite possible that there are additional mode bits that need
to be set, because bits 22 and 23 aren't doing anything at all.
i.e.,
{{{
ok begin-select /pci/@b
ok 0 0 my-space 0200.0010 + 800 " map-in" $call-parent value usbd
ok 7 my-space 4 + config-w!
ok usbd .
ffbd3000
}}}
3 correct read-only and default values, to verify mapping:
{{{
ok usbd rb@ .
10
ok usbd 1 + rb@ .
10
ok usbd 10 + rl@ .
200000
}}}
no change to USBD_PDN when i manipulate the bits:
{{{
ok 800000 usbd 10 + rl!
ok c00000 usbd 10 + rl!
ok 800000 usbd 10 + rl!
}}}
