Morning / afternoon / evening CONFIGURATION: I have a USB keyboard, but use the BIOS to emulate a PS2 keyboard for legacy OS's (in this case, Haiku). PROBLEM: A few weeks ago, I was able to use the keyboard from Haiku. Haven't played with Haiku for a few weeks. With the latest builds, during the boot process, Haiku will crash when the BootScript launches the input_server. INVESTIGATION: - When I remove the /Haiku/beos/system/add-ons/input_server/devices/keyboard file, Haiku will boot normally (but with no keyboard). With this file, Haiku crashes. - When I boot into safe mode (where the input_server is not started), the consoled successfully utilises the keyboard. - The KeyboardInputDevice.cpp file will crash when calling StartMonitorDevice(kKeyboardDevicesDirectoryPS2) in the KyeboardInputDevice constructor. BTW Haiku doesn't check the status_t from StartMonitorDevice() function call. FURTHER INFORMATION: Here is a rewritten snap from a screendump: ps2_hid: init_driver ps2_command cmd 0x20, out 0, in 1 ps2_command in 0x67 ps2_command result 0x00000000 ps2_command byte: res 0x00000000, cmd byte 0x67 ps2_command cmd 0x60, out 1, in 0 ps2_command in 0x47 ps2_command result 0x00000000 ps2_command byte: res 0x00000000, cmd byte 0x47 ps2_command cmd 0xd3, out 1, in 1 ps2_command out 0xf0 ps2_command in 0xf0 ps2_command result 0x00000000 ps2_command cmd 0xd3, out 1, in 0 ps2_command out 0x56 ps2_command in 0x56 ps2_command cmd 0xd3, out 1, in 1 ps2_command out 0xa4 ... active multiplexing not supported ps2_hid: publish_devices ps2_hid: publish_devices() returned NULL ps2_hid: unit_driver ps2: devfs_publish_device input/keyboard/at/0 status=0x00000000 ps2: input/keyboard/at/0 not enabled There is no continuation from here. Any ideas (Marcus, Jerome, Axel)?
