Hm, I don't see this at all.

On a machine with usbcore built in, I have no "nousb" paramater in the
usbcore directory:
	$ ls -l /sys/module/usbcore/parameters/
	total 0
	-rw-r--r-- 1 root root 4096 Oct 25 11:46 autosuspend
	-rw-r--r-- 1 root root 4096 Oct 25 11:46 use_both_schemes

And on a box with it built as a module:
	$ ls -l /sys/module/usbcore/parameters/
	total 0
	-rw-r--r-- 1 root root 4096 Oct 25 11:52 autosuspend
	-r--r--r-- 1 root root 4096 Oct 25 11:52 blinkenlights
	-r--r--r-- 1 root root 4096 Oct 25 11:52 nousb
	-rw-r--r-- 1 root root 4096 Oct 25 11:52 old_scheme_first
	-rw-r--r-- 1 root root 4096 Oct 25 11:52 usbfs_snoop
	-rw-r--r-- 1 root root 4096 Oct 25 11:52 use_both_schemes

It's a real paramater.


As for showing up in /sys/module/nousb/ on both machines:
	$ ls /sys/module/n*
	ls: cannot access /sys/module/n*: No such file or directory

it's not there.

I thought I had seen this sometime in the past, but I can't duplicate it
at all anymore, so is this still an issue?

thanks,
