Looking through this log file, I see usb hub assigned irq 10,11,9,5?
Are you using a usb hub?
Do you have both front and rear usb ports on your computer?
Best to try rear ports first.
Also could be IRQ conflict.
Try looking at...

cat /proc/interrupts

No Hub. I will look for IRQ conflics. I can get Knoppix 5.1.1 to boot but maybe since thats kernel 26.x it may handle the interrups differently?

I tried all the ports rear and side. I will try again plus I will remove the USB mouse. There are two USB ports on the side and one is where I put the USB mouse and the other dsl.

When you put the mod in are you seeing "Waiting for USB devices" ?

If not, then try moving the ash -c "sleep 6" directly inline like this:

if test -n "$WAITUSB"; then
echo -n "${CRE}{BLUE}Waiting for USB devices${NORMAL}..."
ash -c "sleep 6"
echo "${BLUE}Done.${NORMAL}
fi

I can see the Waiting message and it does wait when I use the waitusb boot option.

No I don't see that message at all waiting for USB drives.

I am going to try that. I never lined the script up like that. Will try it that way shortly.

Here is my cat /proc/pci readout

Do you want me to remove the entire usb_wait function and just put in that script or insert that where the sleep 1 is and line it up as you have?

got a /linuxrc : 101 Syntax Error: "|" unexpected.

Here is some before and after script in the linuxrc file. I removed as you can from the wait_usb function all the way down to "}" then just added your script.

Please check it not sure why I got the syntax error.

Thanks
