From 537773e6f10d648928c1f8adbe23a281e8c8ffb8 Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich" Date: Mon, 11 Aug 2008 23:12:24 +0000 Subject: [PATCH] Add support for mcp55 usb and usb2. These both compile. There is an unresolved issue w.r.t. the DEBUG check in usb2. How do we want this in v3? Signed-off-by: Ronald G.
