Hello,
I have an HP ze4145 notebook. I installed LFS 4.0 on it
and I had a problem with the synaptics ps/2 touchpad right
from the start. If I did a simple cat /dev/mouse (link to
psaux) the computer froze. I read someplace that it didn't
actually froze, it just 'blocked' the keyboard so that I
couldn't type anything.
Out of luck, I tried to play with it. I built most of the
kernel as modules and I noticed the moment I did modprobe
usbcore and then modprobe usb-ohci the mouse would work!
I re-compiled the kernel with the 2 USB modules built-in
(no longer modules). The computer booted and once it got
at the console login, I couldn't write anything.
I re-compiled the kernel back, with the usbcore and
usb-ohci as modules and I created a script in
/etc/rc.d/init.d to load the modules at startup, as the
last thing the boot process would do before the login
prompt (/etc/rc.d/rc3.d/S99usb-start). The computer
'blocked' the keyboard again.
So, as of now, I manually load the two modules after
login, before doing anything else. Note I can't just run
my script (the computer blocks) but I have to modprobe the
two, in order.
The script I created does nothing else but
!/bin/sh
/sbin/modprobe usbcore
/sbin/modprobe usb-ohci
I have (most) of the entires in the /dev/usb/, such as the
busses, two mice, two joysticks, one keyboard, one printer
and one scanner. Once I get the usb filesystem mounted, it
actually works. So far, I successfully connected a digital
camera (IXUS 330) and a scanner (LiDE 30) and did things
with them.
Any ideas?
