By the way, the front socket that dislikes the USB 2.0 flashdisk (ehci) feels perfectly happy if I plug and USB 1.1 flashdisk (uhci)... Feels good also if I plug my Digital Camera there... And I've plugged it there thousands of times. Some posts I googled about this kind of errors tend to indicate this would be an IRQ mess ;-)) -- Michel Bouissou OpenPGP ID 0xDDE8AC6E
