My keyboard is repeating char. When I type on my usb laptop keyboard, it sometime repeat char and it only stop if I push the key again. If it's the backspace that repeat, it can erase an entire text if I don't push the key again fast enought. Here is what is enable in my kernel that repport to the usb : # ALSA USB devices # CONFIG_SND_USB_AUDIO is not set # USB support CONFIG_USB=y # CONFIG_USB_DEBUG is not set # Miscellaneous USB options CONFIG_USB_DEVICEFS=y CONFIG_USB_BANDWIDTH=y # CONFIG_USB_DYNAMIC_MINORS is not set # USB Host Controller Drivers # CONFIG_USB_EHCI_HCD is not set # CONFIG_USB_OHCI_HCD is not set CONFIG_USB_UHCI_HCD=y # USB Device Class drivers # CONFIG_USB_AUDIO is not set # CONFIG_USB_BLUETOOTH_TTY is not set # CONFIG_USB_MIDI is not set # CONFIG_USB_ACM is not set # CONFIG_USB_PRINTER is not set # CONFIG_USB_STORAGE is not set # USB Human Interface Devices (HID) CONFIG_USB_HID=y CONFIG_USB_HIDINPUT=y This is the listening of dmesg about the keyboard : input: AT Set 2 keyboard on isa0060/serio0 It say "2" keyboard and I own one only...
