USB Keyboard not detected during Kudzu

I wanted to install Red hat Linux 9.0 on my PC. I started with DIsk 1 but then my USB keyboard doesn't work when the install reaches a point "CD Test".

So during the initial prompt screen where in it prompts for Graphical Mode, Text mode etc I entered

linux nousb

The installation went through fine and my USB keyboard worked fine. ( keep in mind my BIOS setup USB Legacy support is enabled)

After installation it reboots the machine and after reboot it loads the modules and brings up kudzu to detect new hardware from that point onwards my USB keyboard is not working but my USB mouse works just fine.

Please could someone guide me regarding this.

Hi anandjun

Kudzu is there to detect changes in hardware, but USB is not handled by kudzu, but by hotplug, because USB devices can be hot-plugged (plugged-in and out when the pc is running)

If I was you, I'd use a ps/2 keyboard to boot up, and remove the "nousb" command from the kernel commandline in /etc/grub.conf (symlink of /boot/grub/menu.lst), then try to restart with your usb keyboard plugged in.

Boot into single user mode and type: chkconfig --levels 345 kudzu off

Any compelling reason to install a dead OS??? RHL9 is not been support by Red Hat for three years now.

Same suggestion..... FYI: RHL7.X is also a dead OS even longer then RHL9.........

Check the BIOS and set the USB ports to legacy mode. Or install a modern supported OS.
