[ros-dev] Uhci Driver Hacks

[James Tabor]

Hi all,
This is the latest hacks I have for now. I will be out for a week so have fun.
hpoussin is a major help with the pnp code. I'm using it as a guide. Thanks
to hpoussin for making the ioctl code work. You will see some of my hacks, just
ignore them.


hpoussin found a bug in setupapi. I think we do not have cfgmgr32.dll so our
setupapi doesn't forward to it as it should.
