Replying to [comment:9 korli]:
> Gabriel, it seems you made a wrong use of EHCI_USBCMD_ASPMC_MASK and
EHCI_USBCMD_ITC_MASK. They should be used shifted and inverted, and before
ORing another value, not after.
Thanks. I was actually confused as to their use, since they didn't seem
to be doing anything. Now I get it. Clear bits then apply new bits.
Very helpful.
