[PATCH] USB: Fix maxpacket length for ep0 on root hubs
This patch (as591) fixes a rather innocuous bug that has been around for quite a long time: Virtual root hubs should have a maxpacket length of 64 for endpoint 0. I didn't realize it was wrong until I started looking through the endpoint attribute files. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
