The PSU is a Thermaltake. I have two PSUs with less power. Maybe I should try it with one of them? I will try this evening with a old ps2 keyboard. But it would surprise me if this is the source of the problem because the usb transmitter for the keyboard / mouse is used in another computer without problems and the over-current messages are always related to port 7 and 8. Using a different usb port makes no difference... Best regards -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
