USB polling

[Andrew Thompson]

Hi,

The one usb task that is still an issue for 8.0 is the polling
support. The code needs to call into the host controller driver to
check if the usb descriptor has been marked as done and call the
completion callback. I am now traveling so cant look at it, if anyone
wants to have a look it would be fantastic. This is needed for places
where a usb keyboard is used and interrupts are disabled (root mount,
DDB).


regards,
Andrew
