I didn't mean for you to use both CONFIG settings for the same test! The
CONFIG_USB_STORAGE_DEBUG setting was only for debugging the USB drive
failure at boot time. For future testing of the keyboard, you should turn
off CONFIG_USB_STORAGE_DEBUG.
Here's what you can do next: Use the usbmon facility to see what the
keyboard is doing. The instructions for usbmon are in the kernel source
file Documentation/usb/usbmon.txt. You will need to set CONFIG_DEBUG_FS
and CONFIG_USB_MON in order to use usbmon.
Then you will have to do something like this:
mount -t debugfs none /sys/kernel/debug
modprobe usbmon
cat /sys/kernel/debug/usbmon/2t >kbdlog
_before_ the keyboard is plugged in, so that the log file will contain all
the messages. This means you will probably need to use a network login
to start the test (unless you can use a non-USB keyboard).
Do this under both 2.6.16 and 2.6.17 so that I can compare the results and
see what the differences are.
