From 14f76cc7ab75b1c9db036dcd6b247e0dcc8952be Mon Sep 17 00:00:00 2001 From: Matthias Urlichs Date: Fri, 2 Jun 2006 11:48:56 +0200 Subject: [PATCH] [PATCH] USB: new devices for the Option driver This patch extends the "option" driver with a few more devices, some of which are actually connected to USB the "right" way -- as opposed to doing it via PCMCIA and OHCI.
