I installed ubuntu 9.10 netbook remix on my MSI WIND and I'm facing several problems (9.04 desktop edition worked fine before).

- USB mouse not detected (no entry in lsusb) unless if I restart with mouse plugged
- USB key not detected (no entry in lsusb) (not even after a restart when key is plugged)
- Webcam not detected
- Brightness goes up and down automatically

Any idea allowing me to deal with one or another problem suits me.
