From 16f16d117c1eb99451e4c73c87546eef05c66790 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 24 Oct 2005 15:41:19 -0400 Subject: [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.
