Thank you again,
I did what you said. I'd read in a web page about use "SendCoreEvents" for usb mouse, but now I replaced that with "CorePointer" and deleted
InputDevice "Mouse0" "CorePointer" (My old PS2 mouse). But even after this the mouse is not on.
Searching the web for the answer I found a page that teach how to configure usb mice in slackware.
Edit the following file using vi/vim:
vi /etc/rc.d/rc.modules
At the end of the file add these lines:
/sbin/modprobe usb-uhci
/sbin/modprobe hid
/sbin/modprobe mousedev
Then edit /etc/X11/xorg.conf:
We already know what to put in xorg.conf, is the same you told me. The page is
http://www.slackware.cl/index.php?q=node/331. It is in Spanish.
The problem here is that the modules usb-uhci, hid and mousedev don't exists and I was unable to find them in the VL repo nor Slackware repo.
modprobe from terminal or edit the file
/etc/rc.d/rc.modules both failed.
EDITED:
I switched the mouse and the pendrive order, now with mouse in the first usb port the mouse is detected and the pendrive is not. In Knoppix both are detected no matter the ports order, what's the problem? VL bug or some specific incompatibility with my hardware? My Vector Linux Machine is an old one, PC chips, PII 333 MHz, 192 MB-RAM, 2 usb ports. USB is enabled in BIOS. To use pendrive now i have to unplug the mouse first, access pendrive from terminal using cd, transfer data, then unplug the pendrive and plug again the mouse.
If you know something relevant to this unusual case please tell me.
EDITED AGAIN:
Sorry, my mistake, it is a hardware problem. I tried to boot knoppix again and it could not detect nothing plugged in the second usb port. I can't tell when this starts but this is the actual status of my PC. To avoid be without mouse while using the pendrive I configured to mice to control the same cursor. The old PS2 with "CorePointer" option and "Microsoft" protocol, and the usb one as written in my previous posts. I'm using the usb mouse for near everything, only when connecting the pendrive I quit the usb and continue with the ps2 mouse, once I finish I connect again the usb mouse, all without restarting.
Thank you all for the help.
