(corrected) need a hint

Hi all,
i've being using darwin for 2 year on a desktop computer.
Yesterday i bought a new laptop a toshiba r200, it works fine but i
can't install darwin on it. when i boot i get an error saying "usb host
controller halted, resetting" and it hangs here.
tried googleing around but i cannot find anything that helps.
Have u got any solution?
i've spent 2.200€ for this stupid computer and i don't like the idea
that i have to use only windows on it :-(
Thanks
