Hello Dears

I have a DELL Latitude D520. I have a usb mouse and an HP usb printer connetected to it. My OS is Ubuntu 9.04 updated every three days. When switch on the PC the system doesn't laod the usb mouse and printer. After several minutes the mouse starts to work, and in order to get the printer working I have to switch off the printer and then switch it on again.

There is anybody out there able to explain what's wrong?

Best wishes
Pierre
