It uses a synaptics PS/2 touchpad. In the following I'll try to best describe the problem I have. Kernel versions covered: 2.4.19 - 2.4.21pre6 patched with acpi-patch. Distribution: none (LFS 4.0) 1) I compiled the kernel with usb support built-in (not as modules). Upon booting and entering the login prompt, the keyboard is blocked (i.e. I can't write anything with it). If I press the power button, the computer enters runlevel 6 (so it is not frozen) and powers off. 2) Recompile the kernel with usb as modules (usbcore and usb-ohci) and do a script in /etc/rc.d/init.d/ to load the modules at boot time. Symptoms stay as above. 3) Remove the script from /etc/rc.d/rc3.d (e.g.). Boot. Login as root. The keyboard works (yee!). Do cat /dev/mouse. Keyboard no longer works (all three LEDs light up). Reboot. 4) Do step 3 above but don't cat the mouse anymore. Instead do modprobe usbcore and modprobe usb-ohci. The keyboard is NOT blocked. Do cat /dev/mouse. The mouse works (yee). Do mount -t usbdevfs none /proc/bus/usb. The USB filesystem is initialised and the USB works beautifully (tested with a digital camera and a scanner). So, does any1 have a similar problem and a real solution on this thing? Do I do something wrong? Is this a kernel bug?
