From 46414296953410706e917cef9238926084e83a4b Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 16 Feb 2015 12:16:15 -0700 Subject: rpi: add support for Raspberry Pi 2 model B USB doesn't seem to work yet; the controller detects the on-board Hub/ Ethernet device but can't read the descriptors from it. I haven't investigated yet.
