problem using usb keyboard and mouse when install philips usb driver

[沈 方]

Hi,
   I am a novice on Linux.When I try to install philips usb driver on 
redhat 9.0(core 2.4.20), the usb keyboard and mouse stop working after I 
reboot my PC. I followed all of the steps list below to install philips usb 
driver.There is no problems in the compile process. Just after compiling 
the core, when I reboot my PC, the usb keyboard and mouse stop working. How 
can I solve this problem? Thank you!




Setting up Logitech QuickCam pro 4000 on RH 9.0  

Michael Willem's reported that he got the Logitech QuickCam Pro 4000 
working, by just pluggin it in, in his RH 9.0 system. So you might probably 
consider doing that first before following the below instructions.  
This receipe discusses the steps that I took to install the Logitech 
QuickCam Pro 4000 on my RedHat 9.0 Linux System. I haven't experimented 
with all features of this device, but my first impression is good. You can 
access the manual here, but it may not prove to be so useful.  

I followed most of the below steps listed on 
http://www.ap-accessgrid.org/linux/usb.html. However even after following 
all the steps, my camera refused to work becuase of some small 
misconfiguration. This is explained in a later point.  
If you are using Red Hat 9.0, the kernel which comes with it will probably 
have some EXTRAVERSION (for e.g. 2.4.20-13-9). In order to use the camera, 
you will have to start with a fresh kernel. You can download this from 
www.kernel.org. At the time of this writing, the latest version was 2.4.21, 
but i choose to use 2.4.20 becuase the linux driver for this camera, was 
supposed to work only for 2.4.20. So do some background research before you 
download the right kernel version.  
After downloading the kernel, put it in /usr/src/ and untar/unzip it using 
tar -xvjf linux-2.4.20.tar.bz2. You will get a directory 
/usr/src/linux-2.4.20. Make a link to this directory using the following 
commad:  
#>ln -s /usr/src/linux-2.4.20 /usr/src/linux 

Our camera works very well with the philips web cam driver that can be 
downloaded from the http://www.smcc.demon.nl/webcam/ site. Download the 
following files:  
Download the PWC core modules: Check what version is required with your 
kernel version. For our case, we needed pwc-8.8.tar.gz, although I could 
have downloaded the higher versions too. Follow these instructions: 
[pwc-8.8.tar.gz ]  
[shashank at mia ~shashank/temp]# tar -xvzf pwc-8.8.tar.gz  
pwc-8.8/ 
pwc-8.8/kernel-2.4/ 
pwc-8.8/kernel-2.4/ChangeLog 
--SNIP-- 
[shashank at mia ~shashank/temp]# cd pwc-8.8/kernel-2.4/ 
[shashank at mia kernel-2.4]# ls 
ChangeLog    pwc-ctrl.c  pwc-ioctl.h  pwc-uncompress.c  pwc.h        
pwc_nala.h 
philips.txt  pwc-if.c    pwc-misc.c   pwc-uncompress.h  pwc_kiara.h  
pwc_timon.h 
[shashank at mia kernel-2.4]# cp pwc* /usr/src/linux-2.4.20/drivers/usb/ 

Download the PXCX decompressor modules: Follow the below instructions: [ 
pwcx-8.2.2.tar.gz ]  
[shashank at mia ~shashank/temp]# tar -xvzf pwcx-8.2.2.tar.gz  
usb-pwcx-8.2.2/ 
usb-pwcx-8.2.2/x86/ 
--SNIP-- 
[shashank at mia ~shashank/temp]# cd usb-pwcx-8.2.2/x86/gcc-3.2/ 
[shashank at mia gcc-3.2]# ls 
README  pwcx-2.4.20.o  pwcx-2.5.67.ko 
[shashank at mia gcc-3.2]# cp pwcx-2.4.20.o /lib/modules/usb/ 

NOTE: If you don't have the /lib/modules/usb directory, then create it.  
Add the following lines to /etc/modules.conf. 
NOTE: Note the options supplied to pwc module. Here I have specifed the 
frame Capture rate (fps) as 15. This was required to make xawtv work. If i 
do not specify this, xawtv will not detect the camera and aborts with 
/dev/video0: no such device error. 
If in confusion, I will suggest comments out the options field for pwc (and 
let the default values take care. These default values can be read from 
here)  
[shashank at mia gcc-3.2]# cat /etc/modules.conf 
--SNIP-- 
alias char-major-81 videodev 
alias char-major-81-0 pwc 
#options pwc size=vga leds=250,250 fps=25 mbufs=3 compression=0 
options pwc fps=15 mbufs=3 compression=0 
post-install pwc /sbin/insmod --force -k /lib/modules/usb/pwcx-2.4.20.o 
>/dev/null 2>&1  || : 
--SNIP-- 

Now start compiling the kernel. I have mentioned the detailed instructions 
here, but you need to make a few changes in some steps.  
#>cd /usr/src/linux-2.4.20 
#>make clean; make mrproper 
#>cp /boot/config-2.4.20-13.9 .config 
#>make menuconfig 

Turn off the following option 
Loadable Module Support --> Set Version Information on All module Symbols 


In addition check if the following options are selected. (Most probably 
they are)  
USB support --> Support of USB 
            --> UHCI (Intel PIIX4, VIA, ...) 
            --> USB Audio support 
            --> USB Philips Cameras 

Then complete the final step as :  
#>make dep; make bzImage; make modules; make modules_install; make install 

When the compilation is complete, reboot the system in the new kernel 
(2.4.20).  
Download the xawtv application and install it using the normal ./configure; 
make; make install. Start the applications using xawtv.  
Need to experiment more with gnomemeeting.
