Hey everyone!

Here's my problem.I enabled the extras dev repo and installed a linux power kernel+settings and some other stuff.After a while xorg started hitting 100% cpu usage,so i suspected that something from the extras dev repo was to blame.
I started uninstalling things and when i tried to uninstall the linux power kernel (from the separate uninstaller that it created)i got an error that the original nokia kernel could not be restored(..or something similar,cant remember the exact words).When i rebooted the device,it simply wouldnt boot.
Time to flash i thought.Well the problem is that i cant get it to flashing mode(dimmed screen with nokia logo and the usb logo on top right).I tried multiple times,pulled battery off etc,i can only get the dimmed nokia screen without the usb logo.
The flasher stays on "Suitable USB device not found, waiting."
Any ideas?
I tried on 2 computers with windows 7 x64 and got this when i plugged n900

where on earth can i get the Nokia USB ROM driver?Installed NSU,no luck.Installed/uninstalled pc suite,no luck there too.
There are ubuntu and archlinux boxes waiting in case someone thinks that the flash will work on linux and gives me some hints about it.
